Friends

I want to work up some 124gr hollow point loads. I bought a box of Hornady XTP 124gr 9mm bullets.

Again, I got a ton of Hodgdon Clays (not Universal Clays) powder on hand and want to use it. But its hard to find reload data.

Anybody have any data?

I want to use CCI 500 primers, FC brass, Clays, COL will be the standard 1.060"

I'm shooting 115gr JRN with 3.8grs of clays and get some flattened primers so I think I'm maxed out there. I could start at 3.0grs and work up?

Any help would be great.
 
Hodgdon website has data for Clays and a 125gn fmj. Close enough. Start low and work up. Be safe.
 
Bad Bob, hello buddy.

You're over max already, don't you have access to safe load data?
Our two buddies above gave you the right advice, but
also get a few load books. Lyman has Clays loads for 125 grain HP.

I'm not sure where you get the idea that 1.060" is standard.
For OAL, first you get load data from a published manufacturer source,
and you look at the OAL they used in their tests.
For the powder charge listed, you can always load longer
than their OAL but if you load shorter you need to adjust charge
downward appropriately.

Personally, I wouldn't use load data posted on this forum or any other
without checking with published manufacturer's data.
Best to check and double check, and be safe.

I hope this helps. The load data you seek is in Lyman's. Get that manual.
 
Clarification

Thanks for all the info thus far . . . just to clarify.

My current load is 3.8g clays with OAL of 1.14", not 1.060" 1.14" is for the 115gr jacketed round nose.

I'll use 1.060" for the XTP 124 gr, since that is the OAL for the factory load.

3.8gr of Clays, not universal is max, correct, I'm just seeing some flatten on my primers. But I've shot about 400 of these rounds with now problems. However, the gun shoots a little high at 10 yards!

So, if Clays is too hot, then what powder do you recommend? I want something that is inexpensive, readily available and lower grains, like 4-5, so I can stretch out a pound of powder.

thanks

With most faster burning than W231/HP-38 powders, you are going to use less than 5.0 gr powder charge with 115/124 gr bullets. Readily available will depend on what you are able to find and if you are looking to save money, it would be better to buy 8 lb container but I recommend that only after you developed accurate loads first. If you see 8 lb containers of Bullseye/Red Dot/Promo/Titegroup/Green Dot/Zip/W231/HP-38/BE-86, I would not hesitate to buy.

For economy of powder, it's hard to beat Promo. While it only comes in 8 lb containers, it's priced slightly above $100/8 lbs. and as Alliant suggests, I use Red Dot load data by weight. 3.8 - 4.0 gr work well with 124 gr bullets.

But if you want to really economize the cost of reloading, reducing the bullet cost will result in greater savings and then the price of powder will have less impact on per round cost.

If you are simply punching paper/target shooting, switching from expensive JHP/FMJ to thick plated bullets will likely save you around $35+/1000 rounds. Say you are loading 124 gr bullet and since 1 lb is 7000 grains and 4.5 gr powder charge will produce ~1500 rounds. The $50+ savings from bullets should allow you greater powder options - http://rmrbullets.com/product-category/bullets-for-reloading/bullets-for-reloading-9mm-355-12/
 
I'm using the RMB 115gr JRN blems. I think I paid $80 for 1000. Thanks for the tips. Time to shop for powder.
 
you should do some more research on that load data. Your seating depth is critical with that combo. Too deep of a seat will cause serious pressure spike. email hogdon with the exact components you are using and get the info direct.
 
Promo/Red Dot is also a very fast powder and you will be skating on the razor's edge between good case ejection and too much pressure.

Universal/Unique will be perfect and 5 grains +/- a few tenths will work well.
BE-86 may give you even more margin, but you will be needing 6g for a good load, same with Power Pistol. 20/28 is a great alternative to Universal/Unique, but there is virtually no data for it so you'll have to work up loads yourself. I did and found it to need about 5% less powder than Unique for the same velocity and I burns much cleaner. International Clays is halfway between Clays and Universal sort of like Green Dot so you won't be gaining much with those powders.

I've also found that 800X is an excellent powder for 9mm but it meters terribly and just a few flakes equal 1/10th of a grain so you have to hand trickle each case. 5.6g under a 1204g lead bullet was giving me 1135 fps with a standard deviation of [STRIKE]6[/STRIKE]18 fps! I doubt that I'll be buying more unless there is nothing else available (which is sometimes the case).

To calculate whether you will compress the powder charge for a given OAL/COL - http://www.thehighroad.org/showthread.php?p=10045817#post10045817

1) Subtract bullet length from OAL to determine bullet seating depth
2) Subtract bullet seating depth from average resized case length and measure this distance from top of the case mouth down using the end of the calipers
3) Mark inside the case and fill powder to this mark
4) Weigh powder charge

This is your max case fill charge for this particular OAL. If you use more powder than this amount, you will start compressing the powder charge and may spike the chamber pressure.
 
124 gn loads

Have you looked at Power Pistol? I've been loading 124 gn Acme coated (lipstick) RN at 1.105 and 4.9 gn. Don't know prices by you, but I can get 4# for about $81. Gives me just about the same feel as Hornady XTP 124 gn commercial loads, which are my 'summer' carry load. You might look at Longshot as well.
 
While Clays makes a decent powder for low velocity target loads using lead bullets in revolvers and low pressure semi auto cartridges like the .45 ACP it is a poor choice for jacketed bullets in the 9mm or other high pressure cartridges. As others have stated the difference between start and maximum load is minimal an can be only 3/10ths of a grain. Its very easy to get over pressure in the small capacity 9mm unless you powder throws are very accurate and uniform.

Fast powder like Clays also will not drive a JHP fast enough for it to expand reliably for that's what it is designed to do in organic material. While you can use these bullets for target shooting on paper its a waste of a good bullet.

You will be better off purchasing a powder in the mid burn rate for handgun like Unique, Universal, Power Pistol, AA5 or Long Shot, AA7, HS6, Blue Dot on the slower side.

I like WSF and Universal in 9mm. Still on the first lb but CFE psitol seems to be working well for me. HP38/231 si about #4 on my list.
Lots of things that will work, CLAYS is just a bit to fast burning for my tastes in 9mm.
 
Thanks everyone for teh informatin this far. I picked up a can of HS6.

I do have some WST1, anybody work up loads using that powder?

Thanks,

Robert
 
Also, anybody have a reliable load for HS6, lots of varying data out there. I've seen a 10gr difference in the max load.

My incredients

FC brass
CCI 500 Primer
124gr XTP
HS6 powder
 
I would go with the data in the Hornady Reloading Manual, 9th edition. I'm pretty sure I saw some data there for HS-6 with their 124 gr XTP at one time, or email Hornady. I don't have any HS-6 so I dont remember exactly what the load was, but I'm nearly sure there is not 10 gr of HS-6 in the case to start with, let alone a difference of that much. I'm not even positive 10 gr would fit in the case with the bullet seated.

I think you better get some manuals to be sure about this.

[edit] Hodgdon's web site has data for the 125 gr Hornady HAP that may be useful

Be safe.

When I am conducting initial load development with a new bullet, I check available published load data and if I can't find the load data for the same bullet type and OAL/COL, I will use the most conservative start/max charges for my powder work up.

While you are using 124 gr Hornady XTP bullet, as horseman1 posted, Hodgdon used 125 gr Hornady HAP bullet which is very close in construction (HAP has smaller HP nose for more reliable feeding while XTP nose was made for greater expansion) with comparable bullet seating depth.

I use load data for 124 and 125 gr bullets interchangeably as most jacketed bullets vary by 1 gr.

So I would use the barrel to determine the max OAL and feed/chamber the dummy round from the magazine to determine the working OAL and use the start charge of 4.5 gr as indicated by Hodgdon (BTW, Hodgdon also used CCI 500 primer) - http://www.hodgdonreloading.com/data/pistol
125 GR. HDY HAP HS-6 OAL/COL 1.069" Start 4.5 gr (865 fps) 25,700 PSI - Max 5.1 gr (971 fps) 33,100 PSI

Hodgdon does not publish 9mm load data with WST. While it is a popular powder with match shooters, WST can be spikey at the top (probably from powder compression) so be careful if you choose to use WST for 9mm.

With WST, I found powder compression an issue even with 124 gr FMJ/RN bullets using longer OAL/COL. Even using longer 1.160" OAL, higher than 4.0 gr powder charge would start to compress the powder charge - http://www.thehighroad.org/showthread.php?p=9655361#post9655361

To calculate max case fill, if you use OAL of 1.069" and .576" as bullet length for 124 gr XTP, you get .493" as max case fill - http://www.thehighroad.org/showthread.php?t=773402
1.069" (OAL) - .576" (Bullet length) = .493" (Max case fill)
Click to expand...
Using .745" as resized case length we get,
.745" (Case length) - .493" (Max case fill) = .252" (Distance from case mouth to top of powder charge in case)
Click to expand...
With .493" max case fill, you should not be compressing powder charge until around 4.3 - 4.5 gr.

If your barrel allows, I would try to use longer length as my working OAL. So say you can use 1.100" as working OAL, I would start at 3.5 gr of WST and work up towards 4.0 gr and see what the chrono says. If you get around 1000 fps, I would stop and not go any further.

But since you may be working close to compressed powder charge/unpublished loads, I would highly recommend you verify the accuracy of your scale to .1 gr using check weights. If you do not have check weights down to .1 gr, cut 1/4"x1/4" of 20 lb copy paper and see if your scale is sensitive enough to detect one piece of paper (.05 gr) and weigh 2 pieces of paper as .1 gr.

BE CAREFUL ONLY USE POSTED DATA !!!! 10 GR DIFFERENCE IN 9MM LOAD ///???
Here is some Hornady data to look at :)
