I think someone else already asked this question but I can seem to find the thread. Now that I have cleaned, deprimmed and resized a large quantity of low cost brass, I am finding that a majority of the cases are less than SAAMI spec length. Some are only .888 (spec is (.898) Should I trim them all to the same length even if it's short? I assume I'm going to have problems getting a uniform crimp if I don't have all the cases the same length. Any ideas?

Use a taper crimp die. Just take the bell out. In a 45 acp, if the ammo is to be fired in a 1911 type, lead bullets should be seated just in to the rifling.The will give best head spacing. The brass should head space the round, but most, if not all brass is to short.

I suspect that both of you guys have forgotten more about reloading in the last five minutes than I will ever know. Having said that, could you elaborate a little on properly headspacing the .45 ACP? I'm going to be shooting these rounds in a Kimber Pro Carry Polymer (1911 style pistol). I've never reloaded for a pistol before.

The overall length of the loaded round must fit the magazine. Only a lead bullet should be seated into the rifling.There is a fine line between go and no go, .005" to long, and the round may not chamber.Seating a lead bullet into the rifling is not necessery on most guns unless u are trying to get match accuracy from a target pistol. The head spacing on a 45 acp auto pistol should be on the mouth of the case. But most chambers are way to long, the extractor may hold the loaded round in position, or the firing pin will reach out till it hits the primer, eather way the guns always seem to fire. A custom barrel may have a tighter head space, i don't know, only have had factory guns.Maybe someone with more experence can better answer your question.
