I had the same trouble with Rainier plated in .357 mag. I was roll crimping to much and cutting the thin plating. I found a taper crimp die at a gun show for $5 and use that now

I was trying to keep these loads under 1,100 fps so I think my problem was to much roll crimp on a non-cannelured bullet.
