RE: I.B.O. speed or Actual speed
DMorg, the only way to compare an IBO rating to what your bows really shooting is to tell us what bow, poundage, draw length, arrow weight or type, etc.... The actual speed could be anywhere from near or over the IBO rating (for 3D shooters with over 30" draw lengths) to 100 fps less with a shorter draw length and heavy arrows. It appears to me that for hunting with a newer bow around 60 lbs, with average 28" or 29" DL, and mid weight arrows in the 400 grain range, people are shooting around around 250 - 280 fps. An older bow or heavier arrows maybe in the 220 - 230 range.
