Jester, i don't know about those loads, I would have to research a 3031 load for cast 405. It may be O K or it may be something that would blow the rifle up. You are right to pull them down. Cast bullets can be heck on rifling if the rifle is not made for it.
sometimes under charging can be as dangerous as over charging I hear like with 296 or H110...dunno about rifle
more concerned about it coming out of the barrel of my Marlin Lever Gun
