My bow is advertised at 330 IBO. I'm getting about 310, at best.
Yeahbutyou aren'tshooting a 350 grain arrow at a 30" draw length either.
I can get advertised IBO+ speeds out of quite a number of bows. Though many do lie about their actual draw lengths and speeds to artificially inflate their numbers for advertising. They use that little * meaning aproximate.
IfaBemanICS 300 arrow spines out just right for a Bowtech guardian or Diamond marquis, 30"DL, 29" arrow, 125 grain head then it certainly isn't going to spine worth a crap for someone shooting an 82nd airborne, X-force, HCA speed pro, etc...set upat the samespecs.........and the300 is the stiffest shaft thatBeman makes in that line.
If we have an
actual 360+ fps
IBO rated bow this coming year as rumoredthen many people with a 29 or 30 inch draw lengthare going to have a real hard time finding an arrow stiff enough. So, when are the arrow manufacturers going to catch up with the energy levels of todays bows?
Bows are only going to get more efficient and faster in the next few years.
