I bought some factory .45 colt ammo. The one on the left is Hornady the one on the right is Magtech. The Magtech works great in my 73 but the Hornady jammed up my rifle. Notice no crimp or cantilever. I should have known it would jam (dumba$%) as the bullet got pushed back in the case!😡😡
(My reloads worked great too )
My reload with red bullet.
