Too bad about that. It must have seen a whole lot of use. One thing you could do is just go ahead and re-bore it out to 8mm, then just neck up your rounds to 8mm. This creates the 8x54R, a genuine Finnish wildcat.
Mosin-Nagants only come in x54R. That ammo is just as cheap as x39 though and substantially more powerful.Do they make them in 7.62x39 or only that x54?
M2HMGHB, pull out the bolt and take a look down the bore from the muzzle. If the rifling comes to the muzzle edge then it's not counterbored. If it is drilled back and the rifling ends about a half inch or so down then it is counterbored.How do you tell if it's counterbored?
