Keep shooting!! It will get better the more you shoot this rifle. My patches would come out cut and ripped until about first 100 rounds. I have shot .490, .495, .498, .500 and .501 out of mine with different combinations of patching.
I have found my GPR likes the .495 w/.018-.020 ticking, moose milk lube and 60 grns of GOEX Eynsford or regular 3F. This is good for me from 25 yds to 75yds. Past that I do up my powder ten grains per ten yrds to keep a simaler sight picture/hold on targets. I have consistently hit 3 inch steel angles at 85 yrds off hand with this set up. Experimenting is half the fun to me.
I too would put my .50 cal GPR up against what is out there. If I do my part my gun would not miss.
