Load Data Advise Needed For RMR 124 FMJ

[GooseGestapo]

My “accuracy” load for 124’s is 4.6gr of HP38. However, it won’t get 1,180fps. More like 1,080fps., but very accurate.
For that, you’ll need 5.8gr of Unique. You can go as high as 6.0gr of Unique but you have to be mindful of seating depths. And... it’s a +P loading in the 9mm.
For hotter/faster loads, I suggest Accurate #7.

I use the RMR 124gr match winner over 3.8gr of Titegroup and it is a stupid accurate load. It isn't going to be the velocity you are looking for, but it made power factor for me and is the perfect balance of soft shooting ang quick return to target. My girlfriend's 16" PCC shoots 1" groups at 25 yards with it.

5.8gr Unique under a 124gr Xtreme plated bullet gave me exactly 1180fps from a 4" Glock 19. It was amazingly accurate as well. I want my practice loads to feel the same and have the same POI as my carry loads so weak target loads are out. But after trying a little bit of BE-86 in 9x19 I knew I had found "The One." Great velocity and accuracy with very little flash and a very mild report. Pick some up if you come across it. I think you'll be glad you did.
