Hi guys, new here. I have an off the wall question hope someone can help with. I was idly wondering.... if a Russian DP machine gun was converted to fire the British .303 cartridge (another rimmed round) would it be able to use the British Lewis Gun Magazines or is there some reason why it would not work? I do not own such a weapon and my question is conjecture only. It is research for possible use in a fictional story. But I would appreciate if any answers wanted to go into detail.
