An option not mentioned is a shortened 458 Win loaded with 44 cal bullets if you are shooting it out of a bolt gun. If a shortened 444 doesn't work for a lever, I would suggest you shorten a 38-55 case and shoot that out of a 38-55 rifle. Same option exists using a 375 Winchester. As far as bullet jump goes, I would shoot them before setting the barrel back on any of them.
