[QUOTE="Trickymissfit, post: 429369, member: 25383"] If your loading pretty hot hunting loads the short neck on the .260, that means short barrel life just like the .243. The vortex of the flame path meets inside the throat on all the .308 cases, where as the vortex of the flame path is still inside the neck on 30-06 cases. And if you go with the 40 degree shoulder in the Ackley style case the flame path is even better as it's in the first third of the neck. But I'm with you in that I'd go with a plain old generic .280 Remington. Ackley stated more than once that the .308 case (generic) was pretty much an improved case as it came from the factory, so velocity gains were not all that was cracked up tobe. The real gain with the Ackley case concept is longer case life and greater barrel life due to the major changes in the flame path (still not as good as the generic 30-06 case). Myself; if it had to be a 6.5 bullet, then I'd go for the .257AI necked up to 6.5 or 7mm. You get the longer neck, which handles heavy bullets much better than the .260 neck (still not quite as good as the 06 neck though), and you gain a bunch of case capacity. Another case to investigate is the Vias. It's really nothing but an improved 6.5/55, and that rounds really smokes! gary [/QUOTE]
