When I was shooting lead, I found the swc from Berrys to be as accurate as any as well as zero swc's. I've since gone to plated using Berry's 158gr Target HP instead of swc. They are as accurate as cast in all the guns I've tried them in and more accurate in a few. I like the plated for the clean shooting. I use 3gr Bullseye in all my 158 gr swc or plated bullets for target shooting.
