Not too bad. The IBO rating uses a different set of specs than your actual setup. You're shooting a slightly heavier arrow than the rating, and one inch shorter draw length. I'd say your numbers are pretty close.
Well, you could shoot a GT 5575 if the bow was shooting 70lbs max according to the 2006 sizing chart I'm looking at for a 27 inch arrow.I finally got around to putting my Katera on the Chrono and I was a little surprised by the result.
Ive got it at 72#
and a 29" draw..
as for my arrow, check my math..
im shopoting ICS hunters at 9.3GPI 27"
so thats 251 + the 100 grain point so 351, + the noc, bohning wraps and blazers.. no idea what they weight..
took 5 shots, 294,295,295,296
the bow is rated at 330
whats the deal?
