I am trying to tune some new arrows and have them looking good but I am still getting nock high results when shooting bare shafts and fletched arrows. I have lowered the nock point and it is still not correcting it. How far below level can I go before causing issues with fletched arrows?
I am shooting a 45# Grizzly with GT 1535s with 200 grains up front.

If you are below level, you are probably getting a false nock high, caused by the shaft recoiling off the shelf. Run the nock point up to about 3/4", and begin to work your way down slowly, until nock high is at a minimum. That will be your nock point. It is not always possible to totally eliminate nock high.

I have my bare shaft shoot a tad nock high but fletched arrows fly great. If you look at my set up you can see the arrow angled. Problem is if I drop it any I get a false reading and actually lost an arrow from it hitting the dirt and flipping end over end. I will work on it some more during off season, but right now fletched they fly great and go where I want.

Are you shooting 3 under? I could never get rid of nock high totally when shooting 3 under. I shoot split now.
Do what Mcdave said.

I am shooting 3 under.

Wisconsinteacher, that could be our problem. I shoot 3 under as well. I never heard that Mr. fingers thanks.
-
Do what Mcdave said and when it's close add a string knock below the arrow. That usually takes care of knock high for 3 under shooters.
-
McDave's advice is very good. Remember to work your way down in small increments. For nock height, 1/16 inch can make a significant difference.

How long are your arrows and what is your draw length ?

Nock hi may or may not reveal an issue.
Bare shaft impact relative to your fletched shafts should be the focus. Ex..If my bare shafts and fletched shafts consistently share the similar mark at 25 yards, then I pay little to no attention to the bare shaft nock position. Typically, I bare shaft tune much further. When bare shaft tuning out to 30 yards, my assortment of properly matched BH's require virtually no other modifications. Have had one instance where a minor brace ht adjustment was required.
-
I have always suspected target height is also a factor in some instances of arrows showing nock high. For instance, my target ranges from maybe fifteen inches off of the ground up to three feet. The arrow leaves my bow at about five feet in elevation. Common sense says that I am shooting at a downward angle and the arrows in the target will show nock high.
Now, if he is talking about paper tuning, it is another matter but no mention was made as to if he is seeing this in paper or just observing arrows in a target.
-
A consistent nock high, even with nock set adjustments, is usually a sign that your arrow is sliding down the string upon release and bouncing up off the shelf. The cure is to add a second nock set below the arrow.
