Im currently in the earliest of planning for a DG game hunt for 2013 or 14, which I hope to include Elephant, and Hippo and Buffalo. Part of me NEEDS a DR 577NE; but realistically Im more thinking 500NE. Much of this is for the mine is bigger part of me. Its probably safe to say 470 is more than sufficient for even the biggest of the DG. If I were a betting guy, Id have to wager at least a wooden nickle that 470NE is the most common caliber for Dangerous Game double rifles. Id also have to bet 470NE would be the easiest to find if the airlines separated me from my ammo. How often does that happen? I hear horror stories about it and would never choose a wildcat cartridge just because of those stories; but is it really a problem? As long as Im running the paranoid route, How hard is it to come by 500NE or 577NE in an emergency, in say South Afrika, Namibia, Tanzania, etc? Is 470 enough of a standard that its worth sticking with the crowd? Is 500NE enough of an improvement to make the leap? AND will you all say Im reeeeeeeelly cool if I get a 577NE?
