I am learning about my 40 cal. STI open gun. I started with 180 gr. and Universal, know loading 135 gr. and Longshot.Longshot at 8.5 gr. is good, so I thought 9gr. might work better. But it seems to be snappier,but does not seem to work the comp any better. I have hear the 38super guys use small rifle primers. Does that help work the comp?
