First shot with any bow bare shaft I stand close enough the arrow wont hit the bow after the shot, but not much farther! maybe MAYBE 5 steps!!! I like a little fudge room in case the dam thing explodes! (doug fir has a tendancy to do just this, something about its fiber structure and tensile strength it either snaps fairly clean or blows up like an m80). Alum/carbon same diff, I don't care to have one come back and bite me.
The charts USUALLY get you close enough you don't destroy too many shafts, they are a good reference to start with. Buy a group of shafts on either end for testing and give it heck.
I move back from there (starting at 5 or so steps from the target) and once upon a time was able to hold groups to 30 without feathers and maintain good arrow flight. I couldn't shoot 40 to save my life with or without feathers, never have figured that mental block out. We're talking targets here, not game!
