I shoot a bit different than most people aq. I only shoot one arrow repeatedly rather than 4 or 5. This is a bit of a ukraniun way to do it but i have uk blood in me so what do you expect. I shoot fixed broadheads which do not fly the same as my field points at all. So i have sacraficed one broadhead out of the pack and sight it in on one arrow labeled on the fletching #1 with a marker. I get this arrow in so i am nailing the diameter of a skoal can everytime then before going out hunting i put a new head on the arrow. I will shoot a few other arrows as well and whatever one flies closest to #1 will be labeled #2 and so on. For me i dont pattern alot of arrows because if your #1 arrow is dead dead accurate you will kill everytime and making another shot in the vitals not required. My buds all say my arrows fly true and rip in speed but my setup must need some tuning so the arrows/bow is more consistent with different arrows. I just think that even if it is well tuned no 2 arrows will fly exactly the same, its more of a mental thing for me to know exactly where my #1 arrow is headed, kinda a confidence boost. I am not telling you to do this method, its alot more work and dickin around but its what works for me. A 12 inch circle group for me would not be adequate because I am scared that i would get excited while shooting and have a margin for error. I sight mine is as dead as possible to allow for my blind ****** shakiness to move the arrow a few inches.
