Kinda puzzled on this one. After putting the new rest on my Z7 im getting a slight high tear. Ive heard of some people wanting a slight high for some reason but i didnt think that sounded right?!? Before making any adjustment i decided to shoot a couple broadheads just to experiment. Turns out my broadheads are shooting slightly higher (2" at 20yds 3.5" at 30) that the FP's. In most cases i would raise my nock point to fix broadhead issue but wouldnt this increase my slight high tear which i need to fix as well? Thoughts?
Just try it and see. If it works, good. If not go back and then try moving the other way. IMO I don't care in the least about paper. I haven't paper tuned in years. Once I get you BH and FP to hit the same I'm good. Would you rather have accuracy and BH hitting with FP at 40 yards or a nice hole in a piece of paper you thew away?
It is most likely a bow timing issue. Depending on the style of rest, a stiff spring tension can also cause this.
You should move your rest up, knock point down, or you have a clearance issue as tfox stated. I still paper tune. I've found in most cases, if your paper tune is correct then no matter what other tuning method you use, it's on too.
This is where my question comes in. If i move the rest up, or nock point down like you stated this will in fact probably fix the slight high tear in the paper. But the fact that my broadheads are grouping higher than the field points, this suggests i need to go against the previous direction. Rest up, nock point down will only make it worse. Am i correct?
Not necessarily. Shoot your paper at twice as far (or half as far) as you are now. I bet you get a different tear maybe exactly opposite. Your paper is only an instant in the arrow flight. The arrow oscillates and you only get to see it at one spot. Set up multiple papers at 3, 4 5, 6, 7 & 8 yards and watch them all be different. Just move the rest/nock and see. It will take you all of 3 minutes to find out. If it works you are set. If not it is not hard to back to where you were and try something else.
There could be a rest timing issue but with the broadheads already hitting high, I bet it is a cam timing issue. But since the problem started when a new rest was installed, I would eliminate contact first.
Then check the rest timing to ensure there is no fletching contact. Some use foot powder spray or lipstick. A rest that falls too early will sometimes give you a high tear but the broadhead will usually hit low. If all checks out, then I wouldn't be over concerned with it.
