Anyone tell me what powder to use and how many grains fir this bullet ? Thansx

Accurate #5 is what I have. 6.2 grains and seat them at 1.130″.

I started with 4.0 grs Titegroup and was getting 1050fps out of a Glock 19 suppressed with Omega 9K. Would heat up fast so after some research I found 4.4 grs Universal gave me 1030fps and did not heat up as fast. So that’s what I’m running now.

6.2 grains seems hot for 124gr No pressure problem?

I’ve been successful with Power Pistol in my Ruger LC9S and Security 9.
5.6 gr PP
Mixed cases
CCI 500 or Win WSP
1.065 OAL

If I increased or decreased the length by 0.010, accuracy went into the weeds.

I’ve settled on 4.4 grns of Bullseye
My 10 shot string produced
1074 min FPS
1126 max FPS
Average 1101
ES 52
SD 15.6
COL 1.94

Sorry I was using a Glock 19

[Ryan Murphy]

Didn’t read the post correctly. 5.7 grains AA #5 seated at 1.085″ should work really well.

5.5 Power Pistol
1.11 OAL
CCI Small Pistol
4.5” Walther PDP
Max: 1221
Min: 1198
Avg: 1207
StDev: 9.0

Shoots to the same POI as my 124+P Gold Dots, my carry ammo, out to 25 yards.

Anybody using AA7 with the 124gr MPR? 7gr with a OAL of 1.20 was an OK load, but it didn’t plunk in all my barrels. So I’m trying to work up a load with a shorter OAL, and I’m curious if others are using AA7 and at what OAL.
