I bought a factory crimp die for 45-70 off ebay back on September 18th. The seller shipped right away, but it's still sitting at the post office in Sevierville, TN "Pending Acceptance". In the meantime, I was wondering if I could use a crimp die for 45 Colt in a pinch? I loaded up 30 rounds of 45-70 to test, but I wound up having to flare the case mouths because of the plated bullets (something I didn't need to do when loading cast bullets) so now I want to put a crimp on them. I still want to get the 45-70 die but I'm getting impatient.
