Does it ever get perfect. I am real close just with constant tinkering. Im getting tears that are perfect at 6 feet and pretty close to perfect at 18 not sure if I fixed my broadhead problems with the paper tuning. So my question is what should i do next. I made a broadhead spin tester yesterday and they all spun fine. My arrows seem to be spined correctly just not sure what to do next.

Ok now i am grouping just fine with broadheads and fieldtips at 10yds. What would keep them from grouping at 20 and further and how do you fix the problem.

Have you tried walk-back tuning? My BH's and FT's were about 3 inches apart. The BH's grouped well together as did the FT's. After walk-back tuning and adjusting the L-R on my rest, they now group right together.

Any Minor rest misadjustment will start to show up at about 20+yards and get worse as you move back. Walk back tuning helps correct the rest position. Best "fine tune-up" I've ever tried.
