I have had a (Mosin Nagant spell) for several years that I picked up at a garage sell. 1944 stamped on it and it was made in Finland I think. I think this is the same ones that was considered very accurate. As I look down the barrel from the muzzle end the rifleing is very thin and gets heavier towards the action. The reason for the question is I know the rifle was designed for long range due to adjustablity on the rear sight. I was thinking about having it drilled tapped for scope, bolt reworked for scope and then maybe refinish and new stock. Any ideas?
