More and more I'm loving Winchester's AutoComp powder in my semi-auto loads...9mm, 38 Super, 10mm, 45 ACP. Low flash for you compensator boys, thus the name AutoComp. Goes a long ways in number of loads per pound of powder. You fellows may want to give it a try.
Best powder I have founds for 380. 4.2 under Lee's 95 rf is a moderate noise and recoil load that chhronographs 880+ out of my Bersa
Best high performance powder for .32 ACP to match Buffalo Bore ballistics:
.32 ACP Hand Loads, Starline cases, Group 1 Federal 100 primers, Group 2 Federal 200 primers, Min. OAL 0.945”
“Group 1” Loads▪ which don’t exceed factory energy, suitable as a "steady diet" for use in Tomcat and Keltec pistols:
Ammunition ________________Beretta Tomcat 2.4”____Beretta M1935 3.4”

Acc. 31-095T LD#00 2.5 AutoComp__741, 25 Sd___________840, 6 Sd
“Group 2” Loads which exceed “average factory energy” for their barrel length shown, for use in steel frames only. Replacement of .32 ACP factory springs with .380 ACP spring set for same model recommended!
Beretta Tomcat frame cracked in testing these!.
