Greetings.
I chronographed 41 grains of AR2206H with the 145 grain Speer at 2,800 fps in Lapua cases and a 26 inch barrel. Also 41.5 grains of AR2208 with the 150 grain Remington at 2,570 fps in R-P cases in a 19 inch barrel. In the 19 inch 42.5 grains of AR2208 gave 2,710 fps with the 140 grain Remington. Please note that these are all flat base projectiles which maximise case capacity compared with spitzer boat tails.
Regards Grandpamac.
