I have a Finnish M39 that shoots 180gr. S&B ammo in a 1 1/2" group at 100 yards with open sights. I would imagine with a scope and some good reloads, this rifle would have the potential for good long range accuracy with some lighter weight bullets.
I have considered installing a handgun scope on it, which wouldn't alter its' original state and then working on some good reloads for it. This rifle has too much history with it...having matching Sako and crown stamps in all the metal parts, for me to alter its' original condition.
If God didn't want us to eat animals, he wouldn't have made them out of meat.
