I had to pull about 40 rounds of Berry's plated bullets in .500S&W loaded by a friend because I was not sure of the true load data.

About 3/4 of the bullets removed had the copper plating severed 360 degrees around from the deep crimp. I know that plating was coming apart when the rounds were fired and some of it would have certainly gone out the compensator, had I been using one.

I installed one of the non-compensators available here from our forum friend Freedomxxx?
