I’m wanting to build a new rifle for the upcoming 230 & 250 A-TIPs and can’t decide on a cartridge to push them. Narrowed it down to these two cases predominantly for case capacity and brass availability. I’m not ruling out another cartridge if someone can highlight one I should also be looking at. I like the RUM as i can use just a magnum bolt face and not a lapua unit. Also Mcmillan will do a carbon for a RUM and not a Norma action. Not too fussed about the single feeding issue with the RUM. What advantages does the Norma have over this case besides mag feeding?
