Cpt--

Wow, I didn't know I was playing the role of the serpent on that one--looks like you've fallen right into original sin, and a tip of the hat to you for it. In all honesty, you could look for a lifetime and not find another 1903 in that condition. I'm sure it's a pretty early gun--WWI-era or older--so the bore may or may not conform to modern 6.5 dimensions. If it does turn out to be oversized, rest assured there ways around it.

If you haven't handled a pre-war MS before, brace yourself--this gun is about to become the standard by which every other bolt gun is compared, and a lot of other things in life as well...

Few will make grade.

My Sympathies in advance,
Malcolm
