Matt,
You might want to recheck those numbers.......565grs at 283 is 100ft lbs of KE.[:-]

You shoot 30"/70# right?
Even at their bare string advertised IBO speed of approx 320fps that's 79ft lbs of KE......which means , based upon this starting point, if your arrows are really 565grs you can probably expect between 250-255 fps before a peep and nock set style.

Even if your arrows are 465grs 283fps is ALOT to ask even for a speedy bow like the Apex 7, as this would equate to about 83ft lbs of KE.
That's probably a little bit above what the bow can do best case with a bare string.
