It works out to about .470 if you measure right at the crimp. Get a case gauge and use that to help, if you don't have one you need one anyway.

Personally I'd rather have a $20 case gauge than my Les Baer barrel floating around my bench and the rest of the parts disassembled. I guess its one thing if you use it to set up a die but I like checking a few rounds as I go.

On another note why does the barrel need to be floating around and who cares about a Les Baer? It either comes out easy to plunk or it is in a revolver where it needs none! If you pass plunk in the intended gun then the OAL and diameter are good!

If my crimp measures at maximum. 471 I'm good.

Note that the .45 acp headspaces on the case mouth so no inward crimp should be used, just taper enough to remove the flare. Bullets intended for .45 acp use should have neither a crimping groove (if lead), nor a cannelure (if jacketed).

Thank you for all the information, I appreciate it.
I have been crimping at .474 because my federal cases have a wall thickness of .011 when doubled for two sides is .022, the bullet is .452 which equals .474 for bullet and case. Does this sound about right ? Do bullseye shooters use a crimp ? I read on Penn Bullets website that they recommend a crimp of .469 when loading their 200 gr lswc bullets. |

I did the barrel thing until it let me down. I loaded some coated, about 2,000 just a smig too long on 1/50. It took a sharpie on the case and bullet, run in a gauge, scrapping the color off to find it. This after three trips to the range fault isolating. Sharpie on just the case missed it. Sorted easily with the gauge even before I found my error. No one here has any errors but me. I'm amazed. My bullet puller is well broken in.
