For all the hangfires ive had today, My worse group was 1 1/2" @ 75 yards. My best is 1" @ 100 yards. After 10 shots im going to swab the barrel to cut down the gunk. That steelwool i used down the barrel lastnight did one hell of a job. I dont get the build up anymore and the PRB loads smoothly now. Im going to try 6 more shots and then i'll swab it out clean again and try 3 of the 225 grain powerbelts.
