Found that the first 5-6 inches of the muzzle were ruined, i.e. extremely trashed to the tune of .324!.(Wish I knew the bullet in the muzzle test back then!). Anyway it sat in the corner for the last 30 years. While I am not one to hack up Milsurp weapons, I couldn't stand having a weapon that could not be used, shot or hunted with. So, I figured I'd try to make a shooter out of it. The throat and remaining rifling was is good shape. Trimmed the barrel back to good rifling approx. 18". Still putting the finishing touches on it and we'll see how it turns out. Thinking she'd make a handy piece to carry when hunting the dense, swampy wetlands on my property.

I have no idea how the 1st 5-6 inches of the muzzle could have gotten so F'd up?
