Buckfevr, that's basically what I do, but with broadheads vs. field points. I've always gotten my BH's to fly with my FP's using that method.
Nub, I just tried your method(Short distance tuning) and it seems to work well. It's quicker and easier than paper tuning and I can eventually finish up with my BH vs. FP tunign method.
I know that there's more than two guys here that tune their equipment!!....thanks guys!
