If someone wants a .600 NE, a .700 AHR or whatever, all the more power to them. Personally I cannot effectively stalk with a rifle that weighs more than 12 pounds, so that limits the caliber of rifle that I can hunt with. But I would not wish to impose my own personal limitations on others who can hunt with a 15 pound or 18 pound gun and who would enjoy taking game with a true big bore.
