I have a super souped up Mosin nagant and my gunsmith tested the rifle and here were the results. I personally haven't gotten a chance to fire it yet
That was with Winchester white box at 100 yards . I am hoping to work a handload up for this rifle but know very little about long range ballistics. The only reloading I have done was some .45 ball ammo a while back.I was curious if you had any suggestions. The barrel has a 9.5 twist rate. I think the Finnish actually chambered these for 7.62x53r which is essentially the same thing as 54r. I would greatly appreciate any help!
I did order some Sierra Match King .311 174gr bullets at the suggestions of a guy on another forum. As well as some match primers. Thanks for any help!
