Average muzzle velocity for this load from the 8.5-inch barrel measured a respectable 2450 fps. In doing so, this load generates 1199 foot-pounds of energy at the muzzle. Firing the same load from a 16-inch barrel produces 2900 fps and 1680 foot-pounds.

Taking barrel length to 24 inches increased velocity to 3050 fps and energy to 1858 foot-pounds. Testing in extreme temperatures showed velocity to average 2275 fps at -29 degrees F and 2475 fps at 125 degrees F from the 8.5-inch barrel. When fired from a 24-inch test barrel, ATK recorded a group measuring 1.56 inches at 200 yards.

At 1200 ft lbs for the 8.5", it basically performs like XM193 does out of a 20".

Its basically within a SSA tactical load, which a certain internet troll thinks is dangerous and no way would Federal loads reach that.
