Steve, you gotta show us the pictures, or the aricle, or the auction listing or something. I'm sure the action is strong enough to handle the load, and I've seen bolt-action 12 gauges before, but I've never heard of it being applied to a Mosin Nagant!No, I mean there is such a thing!
I just got one of the Polish Radom .22 Trainer Mosin's(1956)...It has no magazine, and a very Unique extractor, The lower 1/2 of the rear of the chamber slides back when you retract the bolt, extracting the spent casing...Very Cool !!!blues - didn't the Poles make a .22LR trainer version of the Mosin? Was it a single shot, or did it have a detachable magazine?
