I hear ya. Been there, done that. My problem with my bow having a higher than average nocking point is that most sights wouldn't adjust low enough to accommodate.I chased a tune all summer between bare, fletched and broadhead. Nothing agreed. Finally my son woke me from my stupor with a simple comment…..tune to get the field point and broadhead hitting the same spot then leave it alone…..kinda stung, but he was right. Took about 2 minutes or less.
Who cares what the setup that gives you want you want looks like?
I use a "results driven" approach. I let the results dictate the actions. I tune my bow and then let the target tell me how well I done. If my groups are tight and consistent with a degree of forgiveness, I feel the job is done. If my groups are open and loose or the bow is overly sensitive, I then recheck the tune and make the necessary adjustments to me or the bow or both.
When I shoot often, I shoot with a higher degree of accuracy, but when I don't shoot that much, I shoot with a lower degree of accuracy. I know where I am on the accuracy scale at all times. So, I know what to expect from my bow/arrows at any stage.
Tuning is mostly misunderstood. People view it as an absolute, like it is either tuned or not tuned. But tuning is more on a perspective scale, meaning the better one can shoot, the better one can tune. One cannot tune better than they can shoot. This becomes a problem with today's low BH short ATA ultra high let-off bows. These newer bows can be harder to get consistent tuning results and require some good shooting skills to get good repeatable results.
One of the biggest issues when group tuning or broadhead tuning is people trying to outshoot their sight pin. If one is using a .19 pin, at 20 yards, this pin is covering a large portion of the target. The best one can realistically expect is to hit anywhere within the pin/target coverage. Hoping to shoot a 2" group when your pin is covering a 10" spot is unrealistic. The way around this is to take a sharpie and draw a thick visible ring on a piece of cardboard with an inner diameter that the pin can comfortably sit it at 20 yards. Make a 4" inner diameter ring and see how the pin sits in it at 20 yards. Do the same for 30, 40, 50 yards until you have the right sized rings for your sight pin diameters. This is a great way to improve one's shooting consistency, repeatability and overall accuracy. ALWAYS AIM WITHIN a target, NEVER OVER a target. This increases spatial awareness and allow you shoot smaller groups than you can otherwise. It also eliminates the sinful peek-a-boo problem. Knowing exactly where the pin is in relationship to the target is an absolute requirement to shooting consistent tight groups.
