The attached photo shows the importance of paper tuning your bow. I normally paper tune my rig 2X a year, or more, especially if there has been any changes, from string replacement, nocking points, changing arrow head weight, and even if I change the draw weight by as little as 2 pounds. Looking at the pic you can see it took me 7 arrows and 6 adjustments to go from a left/up tear to a perfect bullet hole. You can view instructions on how to paper tune here http://www.eastonarchery.com/img/downloads/software/tuning_guide.pdf I then re-sighted my bow with field points. After that I screwed on a couple of broad-heads. This is where the rubber meets the road. If your bow is not perfectly tuned it will show up as poor arrow flight, causing your arrows to impact much differently than your field points. Because of the bullet holes, my broad-heads hit exactly the same as my field points. I am now confident I will not miss unless a little eland fever, gemsbuck fever, kudu fever, zebra fever, wildebeest fever, impala fever, warthog fever, jackel fever, red hartebeast fever, waterbuck fever and maybe even some other fever if it comes into range. Africa is now only 15 days away. Tic...tic..tic..
