Hello all,

I have been reloading for a few years now (mostly 9mm, but also .45, 223 and 308) but only recently started loading 357 and I'm facing some issues. I'm loading plated HBWC but fom time to time (2 or 3 times per 100) I'm getting some crushed cases when seating (I seat and crimp separately). I have loaded 2k TC 357 and never had an issue.
I have tried expanding a bit more, but the issue persists. I'm using RCBS dies with Lee FCD. I currently have the round nose seater plug in, but I see that both seater plugs engage the bullet the same way on the outer rim.
Am I doing something wrong here?

Thanks
