I started reloading 45 acp and made my first test batch. The powder load seems fine but I noted on a couple of rounds, this happened. It's like the case is hitting something and causing a jam. The gun is my kimber 1911 that has never done this before with any ammo, so obviously it's my reloads. My initial thoughts are the crimp isn't enough. I do not like to or feel the need to crimp heavily my ammo since its just range ammo. Second thing might be the case over all length. These I set at 1.24" with a 230 grain fmj bullet.
