I dont know I dont believe its possible with 70# draw maybe with 80# and 65% let off...thats the only possible way. Unless they are using some freakishly new HUGE cam design. Single cam cannot product those speeds. I would imagine its gonna have the limb flex of the PSE X-force, and like mathews famous SOLOCAM I dont know im pretty skeptical I think why Block makes a 400FPS target isnt for mathews its because of the DESERT STRYKER by bowtech 405FPS.

BELIEVE NONE OF WHAT YOU HEAR AND HALF OF WHAT YOU SEE
