crimping problem 45 acp

rrp · December 19, 2009, 11:33 PM

Has anyone had a problem with crimping 45 acp Aguila brass? I have been reloading some range brass. All of the brass measures very close to the same length. The only brass I am having trouble with, is this brass. The cases want to collapse, with just a minor crimp. Some of the other brass I am using are a tad bit longer and are crimping just fine. I've never used this headstamp before so my guess is that it is just weaker. I've loaded thousands of 45 acp before and never had a problem like this. Thanks in advance.

Try a LEE factory crimp die, standard RCBS and others may collapse thicker brass. I ONLY use LEE factory crimp when crimping my loads. These dies are open at the top using fingers to crimp and they are adjustable.

Remove the decapping stim from your sizing die.
Readjust the die for an average case length and try that.
