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.
Oh my your right, I don't even know how I came up with 565. I have the old version of OnTarget2 that doesn't have the update for the A7, so I was fudging w/ all the numbers to come up with something of similar specs, and came up w/ 565 somehow. [:-] I am actually at 30 5/8" but that extra 5/8" isn't going add that much, thats for sure. Looks like I need to be around 450-460.
