Picked Up The Mosin Today

It's 91/30 low wall round receiver from Izhevsk. Made in 1939. Arsenal marks all over the stock and it looks like it might be counter bored, but it's hard to tell because of all the cosmoline down in the barrel. Didn't have time to start cleaning because of "homework" for the real job. The rifling from the breech end looks really bright. The bolt, buttplate and magazine have all been electropencil force matched to the receiver. I'm hoping it's a good shooter because now I know I won't feel bad about giving it the bubba treatment. So, at the first opportunity it's off to the range to see what it'll do.
