I have other "real" long-range rifles (like to put together Savages), but I like to screw around with a Mosin-Nagant build occasionally when I get bored...
Cheap, and fun to play with. But it's near impossible to get much better than minute of angle accuracy even when I get one with a good barrel.
So...I'd really like to get a 6.5 mm. blank, and do a 6.5 x 54R- same caliber that won the biathlon for the USSR in '76...
Brass prep/neck turning would no doubt be a pain in the wazoo, but I'm thinking it would be comparable to the 6.5-.06.
