Re: Scratching my head over this
This is not uncommon .
Nornaly the string nock is slighty higher than the rest when the bow is relaxed.
When the arrow is released a broadhead tends to hold the front of the arrow
down until the fletching can correct this downward angle.
A field tip does not. allowing the arrow to stabilize quicker.
There are several ways to minimize this phenomenon. tune the broadhead virtical
if its a 2 blade.( it helps prevents what is called wind plaining).
Or install full helical fletch feathers ,This stabilizes the arrow faster.
To adjust the nock set I use a bare arrow shaft and shoot through a piece of paper
the length of the arrow in front of me. If the hole it makes tears insted of punching a
round hole then it needs to be adjusted .( If it tears downward from the POI then
the nock is to low)ETC.
One other method is to use heaver field tips and it will be close.
If all of this fails then just count the turns on the limb screws to get the same POI
and live with having to adjust when switching back and forth.
I hope this helps
