I use Lapua .243 brass, necked up to .261+/- .001, for my 260AI. This in an XP-100R with a 14.5" bbl. and a Rem. 700 MTN. rifle with a 22" bbl. has performed very well on thin skinned animals at some long distances. Remington has only one offering in its' '09 catalog. Too bad due to the fact that Remington cooperated with Jim Carmichael to develope this cartridge. It is with great hope that Ruger does indeed follow suit and come out with the 6.5 Creedmore for us 6.5 enthusiats. The popularity of the .260, .260AI and the 6.5-284 has been with long range target participants. I have used my 6.5 platform to harvest many an antelope, whitetail deer and a couple of mulies. None have complained about not being dead enuf.
