I just fired two Axis 340s with blazers cut to 29.5 inches out of a 62lb. bow without any kind of a head on. According to the 5 grain per pound rule this shouldn't have stressed my bow in any way should it have? I didn't notice anything other than it seemed awfully fast :wink: but I'm extremely anal about these things so I just want to hear it from the people that know so maybe I can get some sleep tonight. I do have to say it sure does tear up a bag target with no point on!
