I would like to get some load info on this caliber, and what it is doing out of a 15in. barrel. Most of the info that i have seen has been rifle. The bullets that i am most interested in would be the 75, 85, and the 100gr. Thanks for your time.

MY load for the 257 AI in a 15" encore barrels is 100 Grain Nosler Bal tip over 50.0 Grains of RL19 & Federal 210 Primer with WW + P brass. It has shot a repeatable 1" group at 100 yards with a velocity of 2645 fps. Hope this helps.
