I had a struggle with Powerbelts.. Clean Barrel, dirty barrel, Swab between shots, I could never get any consistency in my CVA Optima W/100GR of 777.........
Last night I shot three times with 250GR Shockwaves & put all three touching about 1/2 to the right of the bullseye...
No swabbing or anything, just load & shoot......
