Ive loaded 22.0 grains of H110 behind the 240 Hornady HP/XTP, length set a shade under 1.610. The Grizzly jammed on every other shot, this gun is almost brand new and only fired a couple of dozen rounds. I have loaded up some rounds with the same load and made them 1.590 O.A.L. I havent fired these yet but am hoping a round a bit shorter may cycle better. It may also be that the gun just needs to be shot a bit more to smooth things out.
Thanks,
Kevin
