Ok. Today was my second time shooting reloads and I chronoed results to see what I have.

Now help me understand what all this means.

FIRST RELOAD. 45ACP

First string of 7 was self-defence rounds. Winchester 230gr JHP
All within 876-883 fps range (erased actual string, but min max is there). As I understand - pretty tight group.

Seconds string of 7 was my reloads. IMR PM with 200gr Reinier plated HP
953, 981, 848, 896, 972, 953, 943

MIN/MAX is like 100+ fps difference! Why? Bad powder? Bad powder measure? Why? Is that a "strong" load? How do I tell?


SECOND RELOAD. 9mm MAK

First string was 8 of self-defence rounds. Hornady fancy HP 95gr
955, 987, 958, 974, 981, 940, 964, 973

All pretty close in speeds.

Second string was my reloads. Missouri Bullet RN 93gr + Unique powder.
866, 898, 806, 811, 881, 902, 829, 816

Still, about 100fps difference between lo/hi!


WHAT CONCLUSIONS should I make out of it? Am I doing something wrong?

I use LCT press and lee disk measure.

Makarov with my reloads was very pleasant to shoot. Soft-recoil, nice smoke :) I guess it's lube from lead bullets? Wasn't too dirty inside, but I have something in a barrel. I think it's leading..

WHAT CONCLUSIONS should I make out of it? Am I doing something wrong?


A bigger "sample" gives more meaningful data. 10 or more rds will be more reliable.
Your Chrono likely gives "S.D." and Max Dev. which you can see in your numbers.
An S.D. of 10 or less is good. Even some higher is fine if they shoot accurately/consistently.
100'/sec max. dev. is much too large in my opinion.

The ones with a fairly extreme max. Dev. "could be" powder drop variations or in the Mak large oal variations in the higher pressure rds.

Unique doesn't always drop consistently from the LEE powder-disc system due to the large particle size. In a small case this can be troublesome.
The disc system is extremely accurate with Ball, Flattened Ball and Small rod powders. As powder particles get bigger--especially flake powders--the drop gets less accurate with small powder drops.


I load 9X19 but not Mak. Those 95gr bullets are barely moving---relatively. Just for grins loaded some 95gr in my 9mm. Added after checking my load records:
95gr Sierra jfn AA#5 6.9grs 1.02"1259Avg 119.6Power Factor (LIGHT LOAD!)
1243-1273
ES = 30
SD =10


Do regular powder-drop weight tests on you scale (Beam Scale) to confirm accurate drops. Especially in the MAK loads, test oals routinely until you confirm the range of oals being produced.

FIRST RELOAD. 45ACP ... (factory) Winchester 230gr JHP ... (reload) IMR PM with 200gr Reinier plated HP
Did you mean IMR PB?

my reloads ... 200gr Reinier plated HP ... 953, 981, 848, 896, 972, 953, 943 (fps)
Hodgdon load data (http://data.hodgdon.com/cartridge_load.asp) lists the following for IMR PB and 200 gr bullets out of 5" test barrel.
200 gr CAST LSWC IMR PB OAL 1.225" Start 5.2 gr (831 fps) 12,200 CUP - Max 5.7 gr (915 fps) 15,900 CUP

200 gr Speer JHP IMR PB OAL 1.155" Start 5.0 gr (798 fps) 12,800 CUP - Max 5.5 gr (873 fps) 16,100 CUP


MIN/MAX is like 100+ fps difference! Why? Bad powder? Bad powder measure? Why? Is that a "strong" load? How do I tell?

I want to try my 1911 Kimber Custom II for IDPA
Since you are trying to develop match load (http://www.thehighroad.org/showthread.php?p=8981497#post8981497), when I tried to develop more accurate match loads, I looked at following reloading variables:

- Bullet weight variance (I wanted same or less than 1 grain)
- Powder charge variance (I wanted same or less than 0.1 grain)
- Longest working OAL to reduce high pressure gas leakage around the bullet

Bullet - Copper plated bullets have harder alloy core that may leak more high pressure gas around the bullet especially if it is sized at jacketed bullet diameters. High pressure gas leakage will slow/reduce consistent chamber pressure build up. Due to this reason, some plated bullet manufacturers use slightly larger diameter bullets depending on the caliber and/or bullet weight. Instead of Rainier plated bullets sized at .451", you can consider using brands of bullets that are sized slightly larger to reduce high pressure gas leakage, especially if your barrel is oversized (Berry's 45 bullets are .452" (http://www.berrysmfg.com/products-q58-c58-Bullets.aspx) and X-Treme's 45 caliber bullets are mostly .452" (http://www.xtremebullets.com/category-s/48048.htm)).

Have you weighed your Rainier plated bullets? If there is a significant variance in the bullet weights, you can try sorting the bullets and range testing the reloads by the same weight group.

Powder - For greater accuracy, I prefer to have my powder charges vary by less than 0.1 grain. If the IMR powder is not metering consistently, as 1SOW posted, you can consider trying powders that meter more consistently in the Lee Auto Disk.

You posted "Bad powder?" Is the age/condition of the powder in question? It should have a fresh solvent odor. If not, powder may be bad.

Cartridge overall length - To minimize the high pressure gas leakage while the bullet jumps from the case neck to the start of rifling, I would determine the maximum cartridge overall length (OAL or COL) and use the longest working OAL your magazine and barrel will allow. You can determine the MAX OAL using the barrel drop test - http://www.thehighroad.org/showthread.php?t=506678


Makarov with my reloads was very pleasant to shoot. Soft-recoil, nice smoke I guess it's lube from lead bullets? Wasn't too dirty inside, but I have something in a barrel. I think it's leading

First string ... (factory?) Hornady fancy HP 95gr
955, 987, 958, 974, 981, 940, 964, 973 (fps)

Second string was my reloads ... Missouri Bullet RN 93gr + Unique powder ... 866, 898, 806, 811, 881, 902, 829, 816 (fps)
2004 Alliant load data (http://www.thehighroad.org/attachment.php?attachmentid=182147&d=1364769070) lists the following for 9x18 Makarov and Unique.

http://www.thehighroad.org/attachment.php?attachmentid=185489&stc=1&d=1371706971

Based on your chrono data for lead reloads, your powder charge may not be high enough to deform the base of the bullet to seal the bullet with the barrel. More high pressure gas leaks around the bullet, more liquefied lube will be blown out the barrel and increase smoking and may increase leading in the barrel from gas cutting/lack of lubrication.

Although MBC 9mm Mak bullet weight is 93 gr, you could use the load data for slightly heavier bullet. Based on your chronoed velocities, you probably need to increase your powder charge. +1 on Unique and Lee Auto Disk. I get variations of ~0.2 grain on several Pro Auto Disks I have.

Chapter 7 of Glen Fryxell's ebook covers the definition, location, cause and prevention of leading - http://www.lasc.us/Fryxell_Book_Chapter_7_Leading.htm


WHAT CONCLUSIONS should I make out of it? Am I doing something wrong?
With your 45 Rainier plated bullet load, you may need to reduce your powder charge (assuming you are using IMR PB powder), powder charges may not be consistent, OAL may not be ideal for your barrel or you may need to try different bullets.

With your 9mm Makarov lead bullet load, your powder charge may not be high enough, powder charges may not be consistent, OAL may not be ideal.

I place mine right at 5 yards. Much closer and the muzzle blast can interfere with readings.

medalguy
June 20, 2013, 12:47 PM
I assume (?) your chrony uses a wire. Set the chrony as far away from the muzzle as you can for best and most accurate readings. You can also use two cords to get it more than 25 feet in front of the muzzle. Military, at least US, measures 78 feet away from the muzzle to totally eliminate muzzle blast. Also be sure to weigh all your test charges and bullets, and keep them as close to the same as possible, as suggested. All the other information given is excellent.

Oh yeah, write everything down in a spiral notebook for later review. Those string recordings will disappear from the chrony.

Katitmail
June 20, 2013, 01:05 PM
bds, thanks for detailed answer!

Did you mean IMR PB?
Yes


Have you weighed your Rainier plated bullets?
No

Powder - For greater accuracy, I prefer to have my powder charges vary by less than 0.1 grain. If the IMR powder is not metering consistently, as 1SOW posted, you can consider trying powders that meter more consistently in the Lee Auto Disk.

It is consistent in "batches". When I do 5 throws and weight it - it is consistent within 0.1 from batch to batch. I didn't weight individual throws.

You posted "Bad powder?" Is the age/condition of the powder in question? It should have a fresh solvent odor. If not, powder may be bad

Powder is fresh, made this year. If I left powder in lee measure for weeks in my garage, will it hurt?

Cartridge overall length
MAK is not picky about OAL - I have it at ~0.980
45ACP is picky. 1.225 was good for barrel test but won't feed. I had to go down to 1.200

Based on your chrono data for lead reloads, your powder charge may not be high enough to deform the base of the bullet to seal the bullet with the barrel. More high pressure gas leaks around the bullet, more liquefied lube will be blown out the barrel and increase smoking and may increase leading in the barrel from gas cutting/lack of lubrication.

Yeah.. But I like the feel of it :) I use 3.6gr of Unique.


With your 45 Rainier plated bullet load, you may need to reduce your powder charge (assuming you are using IMR PB powder), powder charges may not be consistent, OAL may not be ideal for your barrel or you may need to try different bullets.

With your 9mm Makarov lead bullet load, your powder charge may not be high enough, powder charges may not be consistent, OAL may not be ideal.


Ok, so I will try following:

45ACP
1. Reduce load from 5.6 to 5.4 and make 10 rounds hand-weighting them. I will also check bullet weights and try to pick similar ones. For this one I can't realy do anything about OAL :(

2. MAK - Increase load to 3.8 and make batch of 10 weighting each load separately. Leave OAL alone. Won't weight bullets. Lot of bullets have lube all over them, not just gas check. Is that defect or I should expect this from Missouri bullets?

Does my plan sound right?

How important is consistency of distance between gun and chrono? Is it a big deal if it's +-1ft ?

Katitmail
June 20, 2013, 01:08 PM
I use ProChrono Digital. No remote. Instructions say 5ft is OK for handgun. I will try further, but as you see factory rounds show consistant results.

bds
June 20, 2013, 01:27 PM
I have left various powders in the Lee Pro Auto Disk hopper between reloading sessions of several weeks without noticable issues.

For checking chrono distance, on your next range trip, set it farther and use the same factory loads. If measured velocities decrease in ES/SD, then use the chrono farther away.

On the 45 load, you have to use the OAL that works with your pistol/barrel. In addition to the 5.4 gr load, I suggest you consider testing 5.2 gr load also. Don't worry, I think you'll make IDPA power factor even with the start charge.

On the 9mm Mak load, you may want to load 10 rounds of 4.0 and 4.2 gr loads in addition to 3.8 gr load for the next range trip, since you are using lighter than listed bullet at longer OAL which will seat the bullet base shallower which will decrease chamber pressures.

To rule out variations attributed to powder charge variations, you could weigh each powder charge, especially for Unique.

Keep us posted!

Katitmail
June 20, 2013, 01:39 PM
Ok, I got it for 45

About MAK.. I _want_ nice recoiling load. Why do you suggest go higher? To achieve consistency and reduce leading? I actually liked feel of it. It was nice feeling load, not sure how accurate it was though..

stubbicatt
June 20, 2013, 06:47 PM
OP. Did you use empties with the same brass/headstamp? Even with pistol cartridges, having greater uniformity in the size of your pressure vessel will give you greater uniformity in pressures and velocities.

If you have settled on your powder charge, and you have used brass that weighs within 1 grain of each other, you might experiment a little with OAL. IME, unlike rifle cartridges where often one gains accuracy with longer OAL, where the bullet is closer to the lands, in auto pistols it has been my experience that a few thousandths seated deeper, but where it still cycles, will often give you a little bit better uniformity in velocity.

As always, keep a weather eye open for pressure signs.

It is a variable that is worth looking at.

YMMV.

Katitmail
June 20, 2013, 07:50 PM
In case of MAK - it's all once fired PPU brass (I bought factory ammo)

I will try to make 10 "nice" loads. Will make sure OAL, powder and bullets all uniform.

Accuracy-wise I made 100 rounds same way as in original post and they all shoot just as good as factory. Just came back from range.. And yes, they lead barrel for sure. I had 100 so I had to shoot it. I will have to bump up charge to see how it goes.


P.S. Is there places I can buy once-fired MAK brass?

bds
June 21, 2013, 01:47 AM
Not sure how easy it is to find once-fired 9x18 brass but you can buy new Starline 9x18 Mak brass for 500/$83.50, 1000/$142 - https://www.starlinebrass.com/brass-cases/9MM-Makarov-Brass/index.cfm


About MAK.. I want nice recoiling load. Why do you suggest go higher? To achieve consistency and reduce leading? I actually liked feel of it. It was nice feeling load, not sure how accurate it was though..

With jacketed/plated bullets, as long as your slide cycles and spent cases extract/eject reliably, you can stop load development when you attain an acceptable level of accuracy.

But with lead bullets, in addition to above, you want a load that won't lead or minimize leading your barrel. This means you may need to test the full range of load data from start to max to determine which charges minimize leading. If you want a nice recoiling target load at below max load data that will minimize leading, you may want to consider faster burning powders that will bump/deform the bullet base better to seal the bullet with the barrel which will reduce leading.

What other powders do you have?

Military, at least US, measures 78 feet away from the muzzle

No, they used two screens 150 ft apart. The first screen was placed 3 feet from the muzzle, the other 153 feet. This gives you an estimate of velocity at the midpoint between the screens, which is 78 feet out.

Hatcher's Notebook describes this in detail, page 404.

I go about 10 feet indoors for rifle or pistol (my rifle range has some sound baffles you shoot through that protect the chrony a little) and 15 ft outdoors. I have more problems with muzzle blasts coming from the adjoining firing positions than I do from my own.

I have had some batches run +/- 120 FPS for no really good reason. The revolver does this to me more than the autoloaders. The best I ever did was one load with a +/- of 9fps and SD of 4 with 5 grains of bullseye behind a 230gr Hornady FMJ bullet in .45 ACP. No idea why this batch was so good. I usually get a +/- of about 30 FPS and SDs between 10 and 20 with hand thrown loads and brass sorted by headstamp.

Keep trying, and you'll get better. 100 FPS probably doesn't matter much for handgun accuracy unless you are shooting 50yd slow fire, but you can probably do better.

How important is consistency of distance between gun and chrono? Is it a big deal if it's +-1ft ?

Mark your cable and set it up the same every time. +/- 1 ft doesn't matter, but it's still good to get used to doing things consistently from the bench to the range. Some guys keep a brick of one lot of .22 match ammo and the same bolt rifle to verify the accuracy of their chrony every time the set up.

I have IMR PB, bullseye and unique
Here's a post about Unique and leading in Mak.
With a recoil operated gun like the Mak, you'll want a fairly fast powder. Something slow like Unique is just going to leave a mess inside the gun.

My son has had really good success using Win231
I had a Russian Makarov chambered for 380Auto but never shot lead bullets out of it. Doing a quick search, many have reported success with 93/100 gr lead bullets using faster burning powders such as Bullseye/W231 without leading the barrel even for polygonal barreled CZ-82.


2004 Alliant load data lists 3.2 gr as max charge for Bullseye at 920 fps using 100 gr LRN.
http://www.thehighroad.org/attachment.php?attachmentid=185512&stc=1&d=1371816359


I found these posts regarding Bullseye powder work up:

I think this poster meant 100 gr Berry's 380 bullet and probably referenced start/max charges from Lyman #49 for 95 gr jacketed bullet - http://www.thehighroad.org/showthread.php?t=506122
CZ-82, Berry's plated round nose;
2.2 gr. Bullseye- too light won't reliably cycle.
2.5 gr. Bullseye- light recoil, cycles great, ejects 2 to 6 feet.
3.2 gr. Bullseye- heavier recoil, cycles great

Here's a post of 2.6 gr with 93 gr LRN - http://www.thehighroad.org/showthread.php?p=6332859#post6332859
My current load is 2.6 grains of Bullseye with a 93 grain LRN. nice light accurate load.

Many are posting 3.5-3.6 gr of Bullseye as full-power loads with 93 gr LRN
3.5 grains of bullseye with the MB cast bullet is my current loading for my cz-82 mak.


So you may want to try 2.5 - 2.6 gr as start charges and work up towards 3.4 gr and see if you can find an accurate lighter recoil target load that won't lead the barrel.


Here are some other threads that discuss reloading for 9x18 Mak:

I was leaving Bullseye for 9mm match loads :)

What is Unique good for? What kind of rounds? I think people make 9mm LRN with Unique at our club.

Ideally I want to finish this 1lb containers and than buy 8# of something I can use for everything. So far IMR PB burns very clean, very little residue. Same is Unique. My MAKAROV was much dirtier with flakes of unburnt powder after PPU Partizan ammo.

With MAKAROV specifically there is no choice in bullets at all. I would go plated maby (since I'm new to reloading) but Berry discontinued them. Missouri bullet is the only one who makes bullets as far as I know. Price is good for cheap plinking/target load. I got 2k of them, so I have to deal with it now. Bought some chore-boy wipes as well :)

Unique is good for all kinds of loads in a variety of pistol loads. I will actually be attempting to work up loads for my 9 Mak shortly using Unique as it's the only powder I have left on my shelf.

There are plenty of bullets available for the 9 Mak but you do have to do some digging. Speer makes TMJs and Powder Valley (www.powdervalleyinc.com) has Berry's plated 9 Mak bullets in stock last I knew.

Nobody has MAKAROV Berrys, they discontinued it. Speer TMJ N/A anywhere I checked but even it they were - it's like $17-20 per box of 100 which doesn't make sense financially.

At about 7c per bullet shipped Missouri bullet is the only one to make sense to load IMO

In addition to the 5.4 gr load, I suggest you consider testing 5.2 gr load also. Don't worry, I think you'll make IDPA power factor even with the start charge.

Well. With lee disk 0.61 I was able to get 4.9gr, checked 2-3 and loaded 20. Will see what I get out of it.

On the 9mm Mak load, you may want to load 10 rounds of 4.0 and 4.2 gr loads in addition to 3.8 gr load for the next range trip, since you are using lighter than listed bullet at longer OAL which will seat the bullet base shallower which will decrease chamber pressures.

Here I used BullsEye and Lee disks gave me more choices. I loaded 3 batches with 2.7, 3.0 and 3.3 First two batches I weighted each one and third one just did whatever disk gave me. It measures pretty good with Lee disk anyway.

Will see how it goes.

bds,

Didn't want reply in "other" thread about books. Thank you for all the help. Your advice is very valuable.

Regarding books.. Finally got my progressive press for 9mm and going to develop first load. None of the books I have had Unique load fo 124gr plated. Making common sense out of other Unique recepies I see that I need to start with 4.6 gr and keep OAL as close to MAX as possible.

Pretty simple and all I found in books was OAL (available online) and was able to "guess" my starting load.

UPDATE with suggested changes. Still didn't shoot my chrony :)

This time I was shooting at exact distance from chrony. According to my measurement there was 15~16ft from gun to chrony. I don't think muzzle blast was an issue since factory loads were good.

Results:

1. 9mm Luger.

AU: 917, ES: 198, SD: 57

2. 45 ACP. I lowered load as per suggestion and seems like it got more stable. ~4.9gr IMR PB

3. 9mm MAK. Per suggestions I used Bullseye. 0.980 OAL, 93gr MB LRN. Also I weighted and bullets more like 94-95gr

A. 2.7gr
823, 778, 814, 839, 843, 800, 747, 791, 763, 758

AU: 955, ES: 38, SD: 13

Loads 3.A and 3.B were each weighted individually. 3.C was weighted couple times but didn't check all. Looks like lee disk measures BE pretty good. I liked how 3.A felt but looks like 3.B/C should be more accurate in "theory"

Obviously I can't check how leading goes because all I shot was 3 strings. What would you suggest to keep? I need to make 100 rounds and shoot through the clean gun to see how it looks.

I'm happy with how 45ACP load came out. Also it won't make PF of 165000

Will have to increase load on 9mm to get into 1000th

Looks like you are making progress.

2. 45 ACP. I lowered load as per suggestion and seems like it got more stable. ~4.9gr IMR PB

AU: 790, ES: 55, SD: 15

I'm happy with how 45ACP load came out. Also it won't make PF of 165000
Since you were planning to test 5.4 gr, I suggested 5.2 gr of PB for 200 gr Rainier plated HP bullet as you need 825 fps with 200 gr bullet to make power factor of 165000 - http://www.ccidpa.org/idpa-power.html

I would also test 5.4 gr load as well on your next range trip. Once you determine the powder charge that will produce accurate loads and meet power factor requirement, you can always customize the Auto Disk hole to drop that powder charge.

FWIW, if you are looking for an accurate match load, I would consider using other bullets than Rainier sized at .451" (I think smaller diameter allows more high pressure gas to leak and produce less consistent chamber pressures). I would suggest Berry's or X-Treme plated bullets sized larger at .452".


3. 9mm MAK. Per suggestions I used Bullseye. 0.980 OAL, 93gr MB LRN. Also I weighted and bullets more like 94-95gr

Looks like lee disk measures BE pretty good. I liked how 3.A felt but looks like 3.B/C should be more accurate in "theory"

Obviously I can't check how leading goes because all I shot was 3 strings. What would you suggest to keep? I need to make 100 rounds and shoot through the clean gun to see how it looks.
Yes, Bullseye meters with 0.1 gr variance in my Pro Auto Disk. As to which load to keep, I would let the holes on target be the judge. I would guess the 3.0 gr load to produce greater accuracy than 2.7 gr load but if you are happy with the accuracy from 2.7 gr load, then it's up to you.

As to leading, if you are going to get leading, it will happen with the first few rounds. Did you get any leading with the Bullseye loads?


Will have to increase load on 9mm to get into 1000th
I never got Unique to meter well in my Pro Auto disk and finally just settled on a range of 4.6 - 4.8 gr for 124 gr Berry's HBRN bullet while the loads produced 2" - 3" shot groups at 15 yards.

Since you have Bullseye, I would recommend it for 9mm. 3.5 - 3.8 gr with 124 gr Berry's HBRN at 1.135" OAL produced 1.5" - 2" shot groups at 15 yards then work up to 4.0 - 4.2 gr.

I would also test 5.4 gr load as well on your next range trip. Once you determine the powder charge that will produce accurate loads and meet power factor requirement, you can always customize the Auto Disk hole to drop that powder charge.

Yes, thats why I did 4.9 - this is what closest Lee hole did. IMR PB also mesaures pretty good in Lee Pro

FWIW, if you are looking for an accurate match load, I would consider using other bullets than Rainier sized at .451" (I think smaller diameter allows more high pressure gas to leak and produce less consistent chamber pressures). I would suggest Berry's or X-Treme plated bullets sized larger at .452".

I will keep it in mind, thank you for info. I shoot 9mm at matches but now I think about trying 1911. To be honest - I think all of those loads accurate enough. I tried pretty rapid fire at a steel from about 30-35 yards and I hit those 12" plates every time. To me it's accurate enough for sport. I bought 1000 of those bullets so I will have to use them all first. And than I will do lead bullets most likely.

As to leading, if you are going to get leading, it will happen with the first few rounds. Did you get any leading with the Bullseye loads?

Not as much as last time but there was some. This time I took "chore-boy", wrapped it around copper brush and it cleaned out pretty good. Next time I will try shooting couple FMJ's after I'm done - seems like it's another way to keep it clean.

One thing I noticed - gun seems to be much cleaner inside after BE.

I used Dillon 650 which I just got and plan to use for 9mm only. Unique measured pretty consistently, I'm not afraid to use it. I do want to get rid of Unique powder alltogether (and IMR PB too).

Seems like BE will be my "universal" powder at the end. I realize it's not going to be perfect choice but it will be easier for me to keep stock and make it more manageable.

Why not try Bullseye for 45 Rainier plated bullets? When I started reloading 45ACP and 9mm with jacketed/plated bullets, I used Bullseye along with W231 and particularly liked 9mm Bullseye loads.

I prefer to use W231/HP-38 for lead bullets.

I might eventually switch to BE. Just bought another lb at local GS. They had 8lb jugs before but I didn't buy (bad for me). So now I have 2lb of BE and 1 of IMR PB and 1 of Uniques.

I will finish IMR PB with 45ACP and use up all Unique for 9mm. Then switch to BE completely.

I was looking for HP38 specifically but there was none at the store. I will buy some if I see it in a future.

For 45 I got those Rainier bullets because I was eager to try and reload but there was nothing else available. Most likely I will use 200gr SWC that everybody seem to be using. For 9mm I will stick to plated because I can't use lead in my P7. Unless I get another gun.

If you like Bullseye, there are probably many who would gladly trade/buy from you. It is a very popular powder.

Yes, 200 gr SWC bullets can produce some very accurate loads.

Yes, but I'm saying that I will be using BE, I need to get rid of remains of IMR PB and Unique.

With 45 bullets - yeah, it's looking much better now. For $$ reasons I'm most likely going to go with Missouri Bullet or other lead bullets. I just met owner of other company at the club, might give his bullets a try. He said he can size them any way I want: http://bootheelbullets.com/

Ok, with IMR PB and 200gr Reinier I found my load today. It's right at 168000 PF and pretty stable on velocities I get.


Now I'm working up Unique for 124gr RMR in 9mm. Got up to 5.0-5.1gr but still didn't make PF of 125000. 4 inch barrel, maybe in longer barrel it will make it, but not in my gun.

1.165OAL
957, 935,953,836,944,927,930,961,952
AU:932, ES: 125, SD:38

I need to be in 1010-1050fps range with this load.
What would you do? Case looks pretty full with this amount of Unique. Should I try to sit bullet lower to increase pressure or thould I increase load?

No. If you are looking for accurate match load, I would use the longest working OAL for your pistol/barrel.

Personally, I would do a full powder work up with Bullseye powder.

In all my years of match shooting, I never came across a shooter who used Unique. It's a great "do it all" powder but for match shooting, IMO there are better powders. Since you already have Bullseye, I would start there.

But I need to use up this 1lb I got. IMR PB gone, now I need to get rid of this one too. Can't just throw it away..

BTW, 3gr BullsEye in 9mm MAK worked great. I shoot BUG match today and was pretty accurate. Had to hit poppers twice since it isn't that powerful :)

There is some leading in first 3/4 inch of a barrel which I took off with chore-boy on brush pretty easy. I will take this load. At least with MAK I'm settled :)
