Here are some specs Mechdoc sent, the first two sheets have a 429 gr. setup shooting 307 fps with 89.96# KE and the second two sheets with a 404gr setup shooting 312fps with 87.58# KE. This is with 28" arrows but i might be shooting 27" when I get it set up so we will see. I'm shooting aa 28" draw length and should have it dialed in by Friday if the dang thing gets here.
