Clean it well. The chambers typically have caked in cosmoline and you need to get in there and soak it good with hoppes #9 solvent and a chamber brush. Even if it looks clean its prolly not.
Second thing ammo.
Surplus ammo is corrosive. Use very hot soapy water to clean thoroughly if use it. New production brown silver gold bear and winchester white box are non corrosive.
In my mosins winchester white box is most accurate producing solid 1 inch groups at 100. It is also in the same class as 30-06. The bear ammo is a little weaker.
