That Nagant rounde is roughly equal to the .30-06. It definately can be used as a single shot. I dont see why it cant be used in a magazine rifle, the Mosin does it as does the British MSLE. Not sure how but I think if you carefully load them so the rim of the top cartridge is ahead of the rim in the preceeding round it might work. This subject has been hashed over amny times so I am sure there will be some others chiming in.
