I am trying to figure out how to zero this thing, if you can do that with a Mosin. Any advice? Anyone I can call? I have been shooting at 100 meters but all various ammo is high from point of aim, and can't seem to do better than about a plate sized group. The bore and barrel are in great shape and I have tried Czech Silver tip, Bulgy, and the 80's Yugo. Any advice would be greatly appreciated.
