So I managed to score a Storm Lake conversion barrel for my M&P 40 so now I can run 9 too. I haven't wrung it out at distance to see what it can really do yet. I've never really been "scientific" when doing shit like this and I figured if anyone had a system for doing this someone here would.
When you're shooting at 25 do you guys have a particular number of rounds that you always shoot to test the innate accuracy of the weapon? 5 rds, 10 rds per group? Just curious.
