ok, I already posted this in answer to Roskoe's message.
I practice at an archery club which allows me only to shoot 25 yards and 18 yards.
I shoot an average of 270 points ( 30 arrows ) at 25 yards and barely 240 at 18 yards.
I papertuned my arrows and my WB, every arrow shot through paper more than 30 times and each delivered a nice bullethole.
How is this possible ? Have my arrows more time to stabilize at 25 yards than at 18 ?
how's this possible after papertuning ?
