Range Report 175 SMK unstable
I used to shoot 155gr bullets with 49.5 grains behind it. There was so much powder in the case that we had to make sure our seating depth was spot on or it would compress the powder. We actually noticed it because the powder pushed the bullets back out of the case some and I couldn't chamber the...- Roz762

Hello folks. I could very much use some guidance. Just got back from a 600yd mid range f-class competition this morning and I am thoroughly confused. I was told by the feller pulling my target down in the pits that my bullet was key-holing on paper. At first I was convinced he must be...- Roz762
