Remedy for 125 gr Remington UMC 357 jumping crimp
Have some factory UMC/Remington 125 gr .357 magnum ammo. It's locked up the cylinder in multiple guns. I finally realized it's "jumping crimp" to tie up the cylinder.
Unfortunately, it's a value pack, and I've got lots of rounds left.
Should I just adjust my .357 die and re-crimp all the remaining rounds?

I finally pulled the unused rounds out of the cylinder and two had bullets sticking out of the case way beyond the crimp. I realized it's "jumping crimp" to tie up the cylinder.

Thanks, P dog shooter. That's what I think I'll do.
Or just load 3 or however many it will hold before the bullets jump out. And shoot them up.
