It sounds like your hitting your rest with the vanes.
If you are using a hunter rest that is.
The feathers are a lot more forgiving.
Check the clearence of the vanes thru the prongs for contact with some powder.

If after you are satisfied you have got good clearence and your arrows are not hitting where they are supposed to, back to the range. You might try the walk back method with the Broad-heads and get them tuned in a hurry and not worry with the field points hitting the same place at this time. I tried the walk-back method this year and it went surprisingly well. I was shooting at 20- 50 yds in about a Hour.

Good Luck





Good Shooting
