Ok for starters if your goal is to hunt with fixed blades and you want them to impact with your field points it sounds like you are already there. If they impact where you want them, group well and fly good I would quit messing with it. Or maybe try to broad head tune at a farther distance. Often times broad head tuning and bare shaft tuning will yeild different impact points.

And what you didn't tell us is where the bare shaft arrows impact, just how they were sitting in the target. Which is really of no concern unless the are very skewed in one direction. Slightly nock high with bare shafts is actually pretty good and I would be happy with that. That shows that you have good FOC and the fletchings are doing thier job.

When I bare shaft tune I cut the fletchings off leaving the base of the fletching. This is where most of the weight is so your arrows are almost exactly as they would be normally but without the steering control of the fletchings.

Then I start up close like 10 yards or so. And you need to use a soft target so you don't ruin your arrows. I use bag targets for almost everthing. Don't bare shaft tune in a broad head target! When I bare shaft tune I worry only about the impact points in regards to my fletched arrows and how well they group. I do not concern myself with how they look in the target. The arrows will fly different in the air, that is what the fletchings do after all, stabilize arrow flight. My concern is that the bow is throwing the arrows in the same spot shot after shot. I gradually move back as I'm tuning and fine tune as I go. I normally stop at 30 or 40 yards. However if you can get good bare shaft flight at 20 yards you are probably tuned pretty well.

And if I am broad head tuning I do the same thing, but with broad heads instead of bare shafts. DO NOT SHOOT unfletched arrows with broad heads!!
