You may think its nuts, but if your Mosin has a bayonet attached like my M44, make sure it is in the extended position when you fire the gun. My Mosin shows noticable inprovments in accuracy and grouping with the bayonet extended vs. folded. Sounds like a crock of bull.......but after I heard about it, I tried it, and it works. I was told the rifles with attached bayonets were designed to be fired with them extended, and shooting with them folded alters the gravitational pull of the universe in relation to the rotation of the Earth and the triggering of solar flares, or something to that affect (seriously, I had it explained to me, why it would effect the gun, but it was all engineering giberish, which left me dazed and confused) Give it a try, what ya got to lose?
