I decided to start a new thread rather than continue posting in my other one.
So, I was having problems with my bullets being pushed into the casings with my last batch of 9mm. If you held the round between your finger and thumb and squeezed tight enough, it would make a small pop and the bullet would fall completely into the casing.
Someone mentioned that I needed to crimp the casing around the bullet, which I have been trying to figure out. I followed RCBS's directions to the "T" and found that I could still push the bullet in, so I tightened the die down a little more than another 1/8th turn. I can no longer push the bullet in, but I can spin the bullet while it's seated. I pulled the round apart and can see an indention where the crimp definitely took place.
I tried to tighten the die down some more to take out the spin, but I'm concerned with makng it too tight. In addition, once I get to another 1/4 turn in, the bullet starts to get deformed.
I'm using hard cast lead bullets that have a brass jacket over it made be Xtreme (bulk box bought at SW).
My question is: Is it safe to shoot a round like this?
I'm wondering if it's just the material that the bullet is made out of that causes the bullet to spin after being tapered crimped. Thoughts?
