ORIGINAL: JESUS loves archers
I`m not sure I understand the question but If you mean why do I shoot from 100 ,the answer is to shoot better at 90,if you want to shoot better at 40 than quit shooting from 40 and go back to 50 or 60.
Again...WHY? Do you plan on attempting a shot on a deer at 100, 90, 80, 70, etc? If you do, kudos for havin the balls to do it, though I feel it is unethical JMHO. If you don't plan on taking a deer at that distance, why bother wasting the time to shoot that distance on aregualr basis?
