I have been shooting Easton axis 500 at 29" with 260gr up front out of my Hoyt Dorado 45@28 off of a elevated rest with no problems bare shaft groups with broadheads and field points. Now I just got my Bob Lee back it is 46@28 and these same arrow will not tune,I Started nocking point 1/8 high and I have moved it all over the string trying to eliminate the tail high :banghead: I am thing that I might have to build my arrow plate out or try some 400 Axis, I could cut and inch off my Shafts.
I wouldn't worry about tail-high as long as your bareshafts group with your fletched arrows. This is according to O.L. Adcock's website on bow tuning. I find it to be the best info on the subject.

add another nock below - and nock between, see if that works
rraming I have the nock below do you think arrow to weak?
I aint nobody but do you have the option of sticking a heavier field tip in the arrow to see if it gets better, or reducing size. You prolly already know but if you cut that arrow off I would do no more than a 1/4 inch at a time cuzz it makes a huge difference. I would be willing to sacrifice one if I thought it could fix it.
You know I am not sure I am really qualified to help you with that nock problem cuzz I have never seen that but I am sort of new to this. I consider O.L. to be the man on tuning and am happy with my results using his info.
Start with your nock pt. 3/4" hi and work your way down, this will eliminate a false nock hi condition.
Unless you severly cant the bow, tail high/low has little to nothing to do with nock hgt/point wght. How do the bare group with fletched? Quite possibly a false low ast 1/8 high.
