I will measure the barrel and post that info here. As far as selling it, I've never been a rifle or gun hunter. I love handguns and shotguns, also archery hunting so I don't have much use for it.

I have some handguns of my dad's for sentimental value that will never leave my side. As for the Krag, I would rather see it go to someone who appreciates and more importantly will use it.

I knew the drilled and tapped receiver would lessen the value, to what extent I do not know.

Again, I'm just trying to get a ballpark on value which depends on may factors.
