If you can run 100 arrows at a time through a 60 lb. bow, it would seem reasonable that you could go up in draw weight to at least 65 lbs. And at 65 lbs., some of these new speed bows, shooting arrows at 5 grains per pound, should give you the trajectory to shoot one pin out to 30 yards or more. I could almost do this with my 61 lb. bow -sporting an IBO of only around 310 and 407 grain arrows. With a lighter arrow, more poundage, and an IBO up there close to 350 - no problem.
