When testing I was looking for a load for USPSA something about 128 PF.

I did not have a chance to load ladders for everything but my target vel is in a narrow range-> 1020-1050 FPS.
Some of these were loaded before leaving for the range Sunday morning, more tests to be done later.
(also it’s not much fun testing when it’s over 100 outside:eek:, no shade on the range so I know what a egg in a skillet feels like)

Some of the loads failed to make PF so I did not test all of them for accuracy and just included the chrono data in case it might be of some use since I had it. I did test the W572 load for accuracy as I am still attempting to figure what if anything W572 does well....

Don't really want to go much heavier with the AA#2 load and get into +P pressures

Quite happy with the new RMR 124gr in house HPs.
I need to do more testing with charges and OALs but the initail results look quite promising.
Jake has also kindly offered THR mambers a 10% discount on them. (PM me if you need the special 124 HP code)
{ a big Thank you to Jake for this}
Target1.jpg Target2.jpg Target4.jpg

Here are a few targets, standing, both hands no rest.
I had a gun failure at the range, my bleep staple gun broke and my cheap masking tape did not want to hold the targets to the backboard, so more targets later.

I actually messed up the 5.4 BE86 group by correcting my POA to try to hit the center on the last two shots aarrrgg. brain fart.
The WSF group is the best of three WSF groups I shot.
Trying my glasses again, they make the sights sharp but everything else more fuzzy.

PS
Still have some other flavors of the targets printed out so I was using them up.
I like the cross hair one best.

Justin and I shoot this with 5.9 grains of BE86. We are getting about 1250 FPS out of it. This bullet seems to like 1200-1250 quite a bit.
Thanks for taking the time to post this review. BTW, I recently changed the name and description of this bullet for an OEM customer who wants to sell it in stores. It is now the 9mm 124 grain RMR MPR (Multi-Purpose Round)
 
I think it was Jake who recommended the BE86 for the 124 gr. I tried it and love the combo. I love that the combo has a nice feel, shoots good and the BE86 meters nice!

The only "problem" I have with them is getting time to shoot more!
 
Same here. BE-86 has steadily surpassed my reference accurate loads with other powders and I am seriously contemplating replacing WSF I have used for full-power loads with BE-86.

Woohoo! RMR bullets being used for OEM manufacturer!

Nice job Jake!
 
I really like WSF, it just seems to work well for me at all charge weights I have loaded.
More velocity possible with BE86 using listed data but for most of my loads I am not after more velocity.
BE86 or Longshot are my goto powders for MAX 9mm loads.
Normally I get really good ES and SD with BE86, but my pistols just don't seem to like it as well as some other flavor powders.
 
I believe it was 6"

Just adding another barrel length/velocity reference point:
9mm, SP2022, 3.9" barrel
COL: 1.075"
RMR, 124gr, JHP, BE86, 5.9gr, SBPRSP
Average: 1145
ES: 9
SD: 3.3
Force: 361
PF: 141
Velocities: 1147, 1141, 1146, 1145, 1150
 
Don't have the data available at the moment, but I've put 5k of the RMR plated 125s down range over TiteGroup/Clays/WW231/Promo. I have gotten decent results will all of them, especially TG & Clays. Good groups as well.

I need to load some of my RMR in house 124 gr JHPs up with my favorite plinker load, and full power load, as well as try BE-86 with them and see what I get.
 
Dudedog, thanks for posting your results. I always look forward to your detail postings to give me at least something to aim for and/or compare against.

With all this talk about HP38/W231 and how good it is, I finally decided to pick up a pound of HP38 an try it out. I have not loaded the JHP's with it yet, but just loaded some pulled plated bullets to give me some barometer on what to expect. I had loads in 9mm from 4.0gr to 4.3gr, and the ES/SD numbers were very good (19/7.3, 12/5.2, 28/13.2, 20/7.6). I was really impressed with the accuracy, feel and chrono numbers of HP38 in 9mm.

Trying my glasses again, they make the sights sharp but everything else more fuzzy.

I have had the same problem for a while now, but it just seems it got worse lately. I feel your pain.
 
Hp38/win231 used to be my go to powder before I found BE86. It can do any of the pistol calibers with reasonable accuracy and consistency. However, I think it being able to do everything, makes it hard to do one thing perfectly. You won't ever get amazing velocities from the max loads but typically you can get good accuracy. Other powders are a little better if you're trying for the most velocity or highest accuracy but the fact that win231 can do everything makes it a winner in my book.
 
So far, I have tried HP-38/Win 231, TiteGroup and Powerpistol for my 9mm loads, but based on this thread, I just picked up a pound of BE86 to see if I like it.

I have found that Titegroup has been my favorite for 9mm up until now.

I also saw some loads on the Alliant sight for BE86 with .45 ACP. Anyone try it? I have been using HP-38 and Bullseye up until now, and I was just told by someone that they are loving Titegroup in .45 as well. (I just started using the RMR 230 gr FMJs along with other brands of 180 and 200 gr. coated SWC).

I"m really a fan of TiteGroup as well, especially for range/plinking ammo. I set my powder drop in the middle/low end of the load range and it just does it's thing, and it has been a very clean powder in my pistols.

I've used HS6 for my upper end loads with good success, but this thread also caused me to pickup a pound of BE86 to play with.
 
CZ-75d/g43 1.040-1.045 oal/ be86/4.9gr w/ 124gr rmr in house hp/ s&b spp/ speer once fired. Loaded it short for function on my 9mms. didn't chrono yet. Does very well for me in them two! T-7 first then on the dillion sdb to finish out. Load @ your own risk if u do!

I'm going to give this load a try in a 9x19 AR platform and see how it works out. Mine has a 10" barrel, with a 6" flash hider permanently attached, so it will be from a 10" barrel. If it works out ok, I'll give it a try in my Beretta CX4 Carbine (with it's horribly mushy trigger) and it's 16" barrel. Both guns have proven to be pretty accurate, so far, so I'm curious how they'll do with this load.

I loaded up some RMR in-house 124 Gr JHPs this AM and after being called in to work the second time I made a range trip. I also shot two loads I already had made up. My do all plinker load with 3.9 Grs of N320 and a plated 124 gr bullet (S&B primers this time). The X-Treme, RMR, and Powerbond 124 gr HPs all shoot great with this plinker load. So did the old RMR 124 Gr JHP bullet Jake sold/used to sell. The other was an old discontinued Master Match 125 gr JSP at full power using 5.7 Grs of N340. (Pictured)

I loaded the RMR with 3.9 grs N320 (My plinker load), 5.5 Grs N340, and 5.7 Grs BE-86. (I was afraid to start with 5.9 grs BE-86 with this bullet, with its long bearing surface loaded to only 1.070/1.075 OAL.) Turned out to be a good move.

I could have loaded the RMR longer, but many people are saying they have to load them short to plunk. They plunked fine in my Shield, my Colt Series 80 1911, and my RRA AR. I wanted to shoot them in my EMP becaue that is the 3" gun I have been getting numbers with shooting other loads, but my younger son has it, and I may never see it again. The Shield is new to me and I like it more every time I shoot it. The EMP is a better gun in all respects, but it is 3+ times the price as well.

I shot everything with the chrono at 5 yards and the target at 7 yards, like I usually do. I saved the best target to show. (Load # 109: Master Match 125 Gr JSP.) I had some other good groups going, but blew them. :)

Load # 111: 3.9 Grs N320, RMR 124 Gr IH JHP @ 1.070 to 1.075 AOL. All FC brass with a CCI 500 primer.

Shot well but not great. The RMR liked the full power loads better.

Tried to shoot very well, but I kept messing it up. Primers were showing signs of being a bit hot. Some primer swipe. My notes say to back off .2 grs and try again. It shot well in the Shield at 35 yards. Bounced a 16 Oz soda bottle all around, by either hitting it or spraying dirt on it by hitting very close. (The Shield is growing on me.)

Load was too hot!. Showed some primer swipe in the Shield, while in the Colt the firing pin indents were blown back out flush!.

Bullet shot well in all three guns again, and I kept blowing groups again, but it showed promise. Shield shot it well at the berm as well. Recoil was stout in the Shield. Primers in the blowback action AR looked OK.

Thoughts. I am glad I did not try 5.9 grs BE-86 to start, as 5.7 was a bit much.

The bullet likes more pressure/velocity.

It is long (.558 Avg), stubby, with a lot of bearing surface, so be careful loading it short. Adjust charge as needed.

It is going to work well for full power practice rounds.

It should work well at Major power factor for pistol games, and is plenty accurate for that.

It's priced right. :)

Again, I cherry picked the target. :)

Use these loads at your own risk They were made with my load technique with my scale in my little corner of the universe. YMMV.

Start low and work up! (You know, like I didn't this time ;) )

One of the primers from the 5.7 Grs of BE-86 loads. Very close to a pierced primer IMHO. Notice the edges of the primer are still rounded. I haven't seen this from this firearm before.

I was thinking about maybe going to 5.6 (5.4 was giving me over 1100 at 1.08)
hhmmm better go 5.5 first.
They shoot well if the shooter does his part (I only sort of dido_O)
 
The 5.9 grains is a max load in the book and we've even experimented with going beyond that butI've never seen anything like the picture you posted. Was it doing that out of the 1911 as well as the shield? We've been using the LabRadar chrono and your velocity results show pretty much the same thing we were seeing. 1250 FPS with 5.9 grains of BE86 out of 6" barrels. Our loads vary between 5.8 and 5.9.
 
I believe the shortened OAL that Walkalong used will have some bearing on the pressure signs he observed. Perhaps another test at the 1.12" range might be in order to see how much difference it makes.

Hope this helps.
