I've been loading some subs in the 900-1000 fps range and was having accuracy problems at longer distances. For a short time it led me to think all kinds of bad things about my PCCs and/or my abilities. I've been shooting all my life so that was ruled out pretty quick. Some full bench rest shooting of the PCCs with a LPVO ruled out the guns to a point.
Both PCCs are 10.5", 1:10 twist, PSA barrels. After shooting sets from 900 - 1300 fps at 25, 35 & 50 yds I've made these observations
900 & 1000 fps at 25 yds holds decent 1" groups. At 35 yds the groups open up to about 3" and at 50 yds 9"!
At 1100, 1200 & 1300 fps we get .5" groups at all three distances.
Loads are 124gr Armscorp FMJ over HP-38, cci SPP and RP or FC brass.
We are fairly new to PCCs. Moved to them after the local sporting clays facility closed. We shoot a large range of calibers in both pistol and rifle. We have ranges at home. Only competition shooting experience is shotguns.
Is this kind of performance 'normal'?
