I have not paper tested out that far. I always thought that paper tuning should be done at close range so the arrow does not have time to level itself. My bow is paper tuned and properly setup. I am sure some of my issues are user error and failing eye site, but I am looking for every advantage I can have. I was just curious if you thought putting a slight helical in my fletchings would help stabilize the arrow. Thanks for your help. I will have to try paper testing at 40. My groups at 20-30 are almost the same.
