Model '94 "Blowback"?

Model '94 Winchester Trapper .45 Long Colt. Shooting Winchester ammo. Brass has burned powder residue on one side of the brass about 2/3 the length of the brass after firing. Has anyone seen this happen? First time shooting Winchester ammo in this rifle.

I have seen this with 45 long colt before. It can be just the powder not filling the cartridge case and burning on that side or the chamber being loose enough to have a gas leak. The first is okay and not uncommon, the second can be unsafe. Are you firing factory lead or copper bullet heads?

Not uncommon with the 45 LC. It's one reason why people prefer the slighly bottle necked 44-40.

For what its worth, My 2 cents

Cowboy loads do this all the time. Shouldn't be an issue. Thumbs up
