range shooting
one thing i can recommend to help with distance shooting is this
-take a small brush and a bright colored model paint, i used yellow.
-apply a bit to tip of front sight
this helps make it stand out against black/dark targets, i had issues hitting accurately before i did this, after this i hit some nice groups in the black at 100.
and for shooting past 100 i would recommend it highly, that and a light grain bullet...
Safety
the mosins safety system is pulling the rear of the bolt back while in firing position, turn to the left and lock onto the metal plate there, this can be difficult, i would recommend the brass stacker pull ring which mount onto it and allows an easier use of the safety, just a clamp with a ring.
clamp ring
Bayonet
i love mine, but some people take this off to add a add on muzzle break to reduce muzzle rise and flash, also make it louder, choice is yours as its your rifle. do what you want to it.
Cleaning
i would recommend cleaning it repeatedly as cosmoline can be stock in some places and can cause loss of accuracy if its accumulated in barrel. if using the surplus russian ammo, ram a boresnake, or rod with Windex or hopps corrosive ammo neutralizer, Windex is easy to get so i recommend this, it will neutralize the acidic buildup and allow for quick cleaning of the barrel
happy shooting, hope i helped
