Yep.......
(I'm still a techy geek livin' in a stick world)

This number is out of my Black Widow SAV (30.5" @ 62.5 lbs)

515gr GT Traditional XT w/ 145gr tip+ 20grs up front = 200fps (As high as 203 on one shot but most were right on 200) Equals 46ft lbs of KE

640gr GT Traditional XT w/ 220gr tip+ 20grs up front and 50grs added to the rear I need to chrono when I get a chance but if the weight to kinetic energy ratio stays the same this one should still be pumping out there around 182fps.

Is it just me or is that a lot of WhoopA?[:-]
