So i have decided to hunt with a mosin nagant 91/30 and i have a few ? for the experts. I have done a few modifications. The bolt has been made over, the barrel has been cut to 20in and threaded with a jp brake installed. i am shooting 7.62x54 180 grain softpoint winchester ammo. So what can i expect from this rifle in this state? How far a shot is to far? and what kind of knock down power do you think.. Powder burn? velosity? I have changed alot. the lower pics will be the new stock when i get the proto type adjustable trigger with safety to play with from tmney triggers.
