The biggest caliber I currently own is a 6MM Remington and I am thinking of buying a 7 RUM. Looking for opinions on this caliber. Specifically the Remington LSS in left hand. I would be shooting it with the factory tube for the first while, then the plan would be to replace with a 28" match grade barrel and have the action trued. Living in Alberta I can hunt everything from Antelope to Moose and I think the .284 would get it done on all species here. What is the recoil like on the 7mm RUM as compared to a 7mm Rem mag? I would probably have a brake installed once I re-barrel. Or should I step up to the 300 RUM or the 338 RUM. Are any of the RUM's inherently more accurate than the others? I would assume that the 7mm would hold a slight accuracy advantage? On a side-note the guns that I currently own (6MM Rem &6BR) are both tight neck/chamber. Always seeking as much accuracy as I can achieve do you neck turn/tight neck on these big calibers? Looking for opinions. Thanks!
