I have a question about the other guys who have this mould. Sized to .459. I had made up a dummy cartridge to trimmed brass to the crimp groove, and they will not chamber in the 2 45-70s I have here with me. I pulled out the COL gauge, and I'm touching lands at 2.450. what is an average COL on these? Is it normal to have to bury the crimp groove to get the bullet to chamber in a 45-70? I may just use short Hornady brass so I can get a good crimp on my bullets, but I think this is just weird.
Has anyone else experienced this?
