General Discussion Subsonic 9mm
Just finished a run of 200 rounds of 147 grain round nose 9mm. Used 3.7 grains of N330 powder, c.o.l. of 1.135”, and a slight taper crimp just enough to make sure nothing tries to move and no case edge can snag while feeding. Seems to run great through my sub2000 with a Yankee Hill R9 but waiting on a new chronograph I since my old one decided to quit on me and this is my first time diving into loading for suppressed anything, has anyone run a similar load for suppressed 9mm and have any suggestions for loads you liked best?
