Why would anyone want a 26" barrel on a short action cartridge if they were using it for hunting? If you need a longer barrel to gain velocity, get a longer cartridge. The 6.5x284 and 264win mag are right at home with long barrels. The Creedmore and 260 do just fine with shorter tubes.
I personally see no need for any 308 length cartridge to wear anything longer than 22" and 18-20" is even better. If you want more weight out front, get a heavier contour barrel.
