[QUOTE="J E Custom, post: 694916, member: 2736"] There are several powders that should increase velocity in the 260 AI. I would look at IMR 7828, RL17, H1000. 47 Grains of IMR 7828 is a compressed load that reaches 2755 ft/sec in the standard 280. with the extra capacity of the AI you should be able to up the velocity and still be within pressure limits. Also to increase velocity you may need to back off the lands .020 or .030 Thousandths. J E CUSTOM [/QUOTE]
