Congrats on the Katera, the one I tested was a pleasure to shoot, I just wish that Hoyt would have put more quality into the camo process as it just looked horrible.

I agree with Mobow, there is no way that bow would shoot that speed with those specs. According to my OnTarget software, that set-up should produce 279 f.p.s. with just a nock on the string, add a peep and your looking at around 277 f.p.s. From what I am getting, if you were shooting it at 67 pounds and 27.5" draw length with just a brass nock, you would have to be shooting a 255 grain arrow to get 316 f.p.s.
