I got a chance to shoot a BlackKnight today

SPPPEEEED is all I can say!! This one was a 70 pounder with 30 inch mods and I shot a 350 grain arrow through the chrono at 355 fps

I then tried one of my own 452 grain aluminum arrows and it went 321[8D] Now, if i've figured this right, that would be 103.44 ft. lbs. K.E.

That's enough to hunt trophy colosalmonsters!!!!!!!! Noise was not nearly as much as I thought it would be and though I didn't shoot more than about 10 arrows, accuracy seemed good for the bow being not set up for me. It will give your shoulder a work out though!!!
