I got a spanish Mauser from a friend, in 7.62x39, it functions but does not out shoot my Sks, it is rather nice looking, with a Boyd sporter stock and such, 3x9 cheapy scope and I am shooting Norinco Milsurp through it, I have not slugged the barrel yet to see if it is .308 or .311, that is the next step, and then try some gas checked heavy lead bullets in the 180grn range. The rounds are so short compared to the magazine length, that I could load the bullets out 1/2" and not have any problem in the magazine.
Price 125 bucks, if it shows promise with handloading, I'll get a timney trigger for it.
