Great rifles, the Mosin-Nagant. I have only one example--a Romanian carbine dated 1954. Blasty little beast, but a great truck rifle.
Years ago I had a buddy that wanted me to go with him to Russia on some deal he was involved in over salmon fishing and hunting on Kamchatka Peninsula. This was around 1999, and retirement loomed large at that time (long story). The Russian part of this deal met us for dinner in Orange County, and he had the most interesting rifles with him--Mosin Nagant service rifles rebored to 9.3 x 54R. These were guide rifles to be used on bears that lived along the waterways these two yahoos wanted to get rights to operate within.
I came away with two concepts after this meet-up--
1) Anything and everything in late 90s Russia was for sale.
2) I gave a hard NO to any idea of me guiding in or going to Russia. The Aeroflot helicopters I saw in the videos looked like Afghanistan leftover Hind-D models held together with duct tape and baling wire, Oil everywhere, smoke from places it shouldn't be coming from. Pass.
Cool Mosins, though.
