200yds is pretty well point-blank for any center fired cartridge so setting a 500yd limit pretty well leaves the selection wide open without providing a little more information like what the target species would be. Which has been said by others already. That said...
The .264 cartridges are phenomenal. The B.C.'s, sectional densities, and terminal performance of today's modern bullet designs easily give a 500yd effective range for all North American game save the ginormous Alaskan varieties of moose and kodiaks. If you reload, consider a long action 6.5x55 Swedish Mauser on a modern action as you will be able to magazine load any bullet at any seat depth which is crucial for VLD style projectiles that are seat depth sensitive and achieve velocities within 50fps of the Creed or 260Rem. The 140gr Berger Hunter VLD on 44.4gr Vhit N-160, CCI 200, Win cases, seated .005 off lands exits my 700Classic at 2750-2800-ish (5280ft elev. atmospheric variables depending) fps and carries 1400lbft of energy to 500 = dead elk, moose, black bear, mulie, white, antelope, coyote, 'chucks, Pdogs, gophers, etc. Kicks like a .243 so your shoulder won't be punished. Don't reload? Then the 6.5 Creed will offer ballistics within 50fps of the 6.5x55 or 260Rem from the widest available selection of factory ammo in the .264 caliber family.
