Still working out a load with my new 280 AI. Of the following powders, using a 140gr. Accubond, H4831SC-IMR4831-RL22-23-26 which would generate the most velocity in a 26" barrel?
Haven't had a chance to finish the load development, but at 200 yards, it's looking promising. 145 Barnes LRX.I had the exact same velocity between 23 and 26 but 23 was more accurate.
