I personally, stay away from the tubular fed magazines because I don't feel they are safe. I knew a guy that was a very avid shooter/outdoorsmen. He had a tubular fed 22lr that clicked, he thought it was empty, he goes to reload it, it decides to fire (coulda been the gun or faulty ammo, no one is sure).....struck him in the chin area, an lodged in his brain. Not a very good way to leave the world.
