I don't normally load 44 caliber 180 grain Hornady XTPs over H110/W296 because it's a stupid amount of powder for that bullet. But just for grins, and to finish off a can, I loaded 8 of them over 30.5 grains of W296. That's one grain shy of Hodgdon's published max. I shot them out of a Henry 44 Magnum carbine today. The mean velocity for 5 rounds was 2225 fps with a standard deviation of 13.1. Seemed much louder than anything I'd ever shot out of that rifle before, but the recoil didn't seem all that different, and the cases looked OK. Seemed accurate enough, too, though it's obviously way over-speed for that bullet's terminal performance envelope. Worked great on a sporting clay at 65 yards, though. Went right through a paper target, too.
