wwillson Posted November 10, 2009 Report Share Posted November 10, 2009 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?Wayne Quote Link to comment Share on other sites More sharing options...
RLH70 Posted November 11, 2009 Report Share Posted November 11, 2009 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. Quote Link to comment Share on other sites More sharing options...
steves Posted November 11, 2009 Report Share Posted November 11, 2009 From the Wilson Combat Auto book specs .469" . As RLH70 mentioned a taper crimp is proper. Quote Link to comment Share on other sites More sharing options...
wwillson Posted November 11, 2009 Author Report Share Posted November 11, 2009 Steves,.469" measured at the case mouth?Wayne Quote Link to comment Share on other sites More sharing options...
woodsoup Posted November 12, 2009 Report Share Posted November 12, 2009 Yes sir! That leaves enough for the case mouth to "catch" in the chamber. Quote Link to comment Share on other sites More sharing options...
Dan1045 Posted December 12, 2009 Report Share Posted December 12, 2009 You guys have got me beat, I have never measured any 45 I have reloaded. Just checked with a caliper against a factory round, set the die and started reloading. Made over 20k rounds and never had a problem. (Took lots of years and lots of shooting)Dan Quote Link to comment Share on other sites More sharing options...

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.Bob Quote Link to comment Share on other sites More sharing options...
RLH70 Posted December 12, 2009 Report Share Posted December 12, 2009 Yeah, and if you don't control the OAL and crimp during reloading you end up with feeding issues and stovepipes. Quote Link to comment Share on other sites More sharing options...
