4 seventy

What do you think caused the misfires? It seems you are thinking it was a compressed load? didn't the primer go off?

I know what you mean though about hangfires. I have an old 6.5 Mannlicher and a fellow in BC gave me 6 boxes of old Canadian Ammo for it. About every third one would go click and then fire in about 5 seconds. Very unnerving so I just pulled the bullets for the brass.
