ORIGINAL: OKbowhunter20

2007 Browning Myst rated at 309 IBO
63 lbs.
27"
366 grain arrow
D loop, peep w/tube
Factory String
QAD Rest

EDIT: I would like that link fingerz, thanks.
Here's how I do it.

309 IBO subtract 14 fps for 7 LBs under 70LBS = 295fps, then subtract 22 fps for 3" less than 30" draw= 274 fps. Then subtract 6 fps for 16 grains over 350 gr arrow= 268 fps, then subtract12 fps ford loop/rubber hose peep = 256 fps. Dude, lose the hose on your peep and you'll bearound 264ish.
