There is nothing to be disappointed about in that speed. If you are shooting 292 with 425 grain arrows, then you'd be around 317 fps at 350 grains. That's a hell of a lot of kinetic energy. I shoot those same arrows, you'll be happy with those and you wont have any problems breaking a little bone...lol

Great Bow....you know how badly the shorter draw guys would love to get that kind of speed with an arrow that heavy...lol

How long are your arrows? I shoot the same arrow at 28" with 2" Quickspins and 100 grain tips. I weighed mine on a digital scale and they are 450 grains. Just curious...you may be a little heavier than 425 and that makes the speed more impressive.
