How much roll and/or taper crimp for 45ACP

All,

I reload for the 1911 in 45ACP. Most of my reloads are 230g RN that I cast from wheel weight lead. I put a very slight roll crimp and a very slight taper crimp on with the Lee factory crimp die. My crimps are so slight that you almost can tell it's been crimped. I believe the Lee factory crimp die full length crimps enough that the bullet doesn't move from the recoil. I'm wondering if I have enough crimp as there are times when I will get a fail to feed, but I just bump the slide ahead and keep shooting.

How much roll/taper crimp to you put on your 45ACP loads?

I never roll crimp my 45ACP rounds since it headspaces on the case mouth, I use a Lee factory crimp die and taper crimp to .470"-.471" on lead or jacketed bullets.

Make that supposed to headspace of the case mouth! If they're a bit short, or over crimped, they end up headspacing off the junction of the extractor and the rim.
