So far the only one I' ve seen in action was at the ATA show. 70lbs, 30" draw shooting a 225gr arrow. The point was to prove it would stand up to the occasional dry-fire or extra light arrow. The pieces went across the chrono at 417fps. Mostly, you can be asured that the bow won' t shoot 400fps in the real world because not very many people can get arrow weight that low in the first place, and certainly not a hunting arrow.
