While visiting with family this past weekend,my brother took me to a pawn shop that he does business with.This guy sell's mosin's for $300.He also showed me a 3 ring binder with 2 bullet holes,touching,so close they could be one.He told me that was from chambering and firing a 308 win in a mosin at 100 yards.Well I told him he was full of dog poo,he got mad and I left.This same guy a few weeks ago, sold my brother a pistol chambered for the 9mm Largo,then sold him a box of 38 super's to shoot.Told him it would be good.I told brother to not shoot them it was not a good idea.This character seems to have the impression that,if it will fit,it will shoot.Now I have never tried the 308 in a Mosin,and I don't have very much experience with the 9mm Largo.Any thought's or input on this?
