The Creedmore was designed to allow the use of VLD bullets seated long & still feed from the magazine of a short action, as in the 300 rapids event of across-the-course Highpower.
The .260 will shoot VLDs just fine, but is better at it when the bullets are seated long for single loading as in prone slow fire like F-class and Highpower Mid & Long range events. Go to a long action and it shoots VLDs loaded long even from a magazine.
Hunting was never part of the equation in designing the Creedmore. Not that it can't be used, just that it holds no significant advantage over the .260 in hunting situations.
