First off< I am not a regular plated bullet user. Years ago I used some Berrys bullets but then just went with FMJ, Cast lead and then coated lead,
Joined a new indoor range (usually shoot outside) and needed to make some ammo look like "factory" so I bought some RMR Plated 158 gr FN for the 357.
I "aged" the bullets so they where not so shiny bright to look more like fmj.
Anyway. folks need not worry about crimping these bullets. I did a practice round and crimped the heck out of it. More than any crimp I would use on any bullet!. No cracking or splitting. I then took a Dremel and cut the bullet in half (sorry no picture) the plating held, no problem and seems pretty substantial.
So do not worry (IMHO) of putting a normal roll crimp on these bullets
