So as stated in an earlier post, I purchased a Type 53 Mosin Carbine today from my local gunstore. Before I bought it I took a look down the barrel and could see it was filthy, but it had alot of unique things about it (including the war trophy documentation from the Vietnam war). Upon further inspection and cleaning, it appears that the rifling in the barrel is all but gone. What does this mean for my weapon? is it still safe to fire? will the accuracy be dramatically decreased? Any advice helps
