Thanks guys! I plan to sell this and I just knew some Mosins were more collectible, and therefore more valuable than others, but had no idea which was which. I think the picture of the bore makes the rifling look worse than it is, but as pointed out, it is counterbored. My friend that I got it from showed me some targets long before he sold it to me where he'd shot some 1-2" groups at 100 yards with iron sights. I was kinda impressed, considering.
