There is a bit of fletch on my rest but i was shooting today and it seems the farther away i shoot the more tighter i group not sure why, but how do i fix the wearing of fletches, i know when buying my bow i had to shoot 10 different arrows and these are the ones i ended up with. i did what ever the archery shop told me to do to hold my bow to shoot it and so on but for now a up close shot sort of fish tails, further away it straighens out. crazy but i like it but what i dont want to do is this fall wound and lose a deer...........
The farther the arrow gets from the point of initial contact the longer the fletchings have to correct the error in its flight. That's why you're seeing tighter groups farther away from the rest. Definitely a fletch contact issue. You should be able to twist the nocks slightly in the shaft to get the fletching lined up between the rest prongs.
If it's hitting the base of the rest rather than the prongs you either need to re-time the drop of the rest or rasie the rest slightly and the nock set equally.
