[QUOTE="edward hogan, post: 2039520, member: 1341"] Great thing about the AI, aside from great velocity gains with heavy bullets, is better case life due to enhanced shoulder angle of 40*. Of course, can get that, almost, with the 284win which is standard at 35*. The last Hodgdon hardback manual (#26?) shoes .30/284 and .30-06 data as interchangeable. I guess it's same for the .280rem and .284win. Gonna rebarrel? Looking for primarily longrange performance W/Heavy Bullets? Using a standard action with a .284win variant gives you better powder performance and much more room in the magazine for loading long bullets without protruding into your case area. Bullet weight of under 150gr acceptable? The 6.5/284 is a Very Proven Performer. Much greater selection of bullet weights with a 7mm though. One last thought is barrel longevity. The .308win and .30-06 are two great performers in this dept. The .30/284 would seem to offer all the benefits of standard 06 velocities, better case life and enhanced accuracy due to better case fill-optimum size, and the 5-7k barrel longevity. Use a long action and you got enhanced bullet seating options. What's not to like? [/QUOTE]
