Sounds reasonable MaxHenderson. My Halon 32-6 is getting 307 at 5.2 grains per pound at 27" of draw length and 68 lbs of draw weight. The same bow at 7.1 grains per pound clocks 270 fps.
It’s a canon... it maxes out at 84# and the arrows are well north of 300FPS. I don’t shoot it that fast for tuning reasons and ability to draw in awkward positions.
