Got a newb question for all of the reloading vets out there. I'm getting ready to reload 9mm rounds with some MBC 115 grain LRN bullets. I haven't picked up primers and powder yet, but I've been playing with the press (Lee Pro 1000) and dies to familiarize myself with how everything works before I start reloading live rounds.
My original experiments with seating and crimping the bullets seemed to be putting on a bit too much of a taper crimp. When I would use an inertia puller to pull the bullet, there would be a small indentation ring around the base of the bullet above the lube channel. Maybe 1/32'nd of a inch. It would take 3 good whacks on the bench to get the bullet out.
Since then I backed the die out, and moved the seating plunger in a bit, and now it only takes one whack to pull the bullet, and I have a small line maybe halfway around the bullet, not even a full ring.
My question is, with cast bullets, is it ok to have a little indentation on the bullet after crimping, or should there be basically no visible signs of the crimp after pulling a bullet?
I don't want excess pressure, but I don't want the bullets getting loose while in the magazine either.
Thanks for any help!
BTW, I've got the Speer and Lyman manuals, and the ABC's of Reloading, but I can't really find anything that addresses this question.
