9mm crimp on Dillon 650

[baranski]

How much of an impression should the brass leave in the projectile?


How tight does the crimp need to be?


I'm fitting in the case gauge, but do I need more crimp?

I am new to reloading and started with 9mm. My first 50 reloads fired fine. What I found was that rounds not crimped properly won't pass the plunk test. Adjust the crimp until they pass. Anyone, correct me if I am wrong here. I am using a Lee turret press.

Dillon dies? Normal to get a hour glass look. Its a tapered case. Dillon dies do a good job resizing to the point of the projectile sometimes looks bulged at the base.

That's where I stopped with the crimp, once they passed the case gauge.

I like to crimp my 9mm @ .379 for a .356 diameter bullet. check out the crimp calculator on the Dillon site.

Thanks GB, that helped.

Hope the OP isn't trying to crimp a plated 9mm bullet.

If you can just see it, that will be ok, DON'T let it dig in.
