Problem: My broad heads are shooting tight groups, but consistently 2-3 to the right of my field points at 20 yards. The up and down impact is the same, just the left and right is off.
Here is my equipment setup:
Mathews Z7 Bow, 62lbs/27.5
Carbon Express Maxima Hunter 350 arrows, 28” length, 2” blazer vanes, right helical
G5 125 grain Montec Broad Heads
QAD drop away arrow rest
Here is what I have tried:
1) Arrow rest was aligned for center shot and paper tuned.
2) Bow was sighted in for field points at 20 yards – I am grouping 2” groups with field points.
3) Switched to broad heads, G5 Montec 125 grain, POI was low 1”, right 2-3”
4) Moved my rest up slightly, broadheads and field point impact same height.
5) Moved my rest left 1/16 inch, no change in impact difference between BH and FP.
6) Continued to move rest in 1/16 increments to left, still no change in 2-3” difference. Moved the rest a total of ¼ inch left of center shot.
7) Reset arrow rest to center shot, still 2-3 difference.
8) Went against conventional wisdom and moved arrow rest to RIGHT 1/16 off center shot, BH still shooting 2-3 to right of field points
I then figured my arrows might be over spined so here is what I did next:
1) Switched my arrows to Carbon Express Maxima Hunter 250 arrows (lighter spine), 27” length, 2” blazer vanes, right helical.
2) re zeroed in for center shot and was shooting 2” groups again at 20 yards with field points.
3 Switched to broad heads, G5 Montec 125 grain, POI was right 2-3” again.
4 Moved my rest left 1/16 inch, no change in impact difference between BH and FP.
5 Continued to move rest in 1/16 increments to left, still no change in 2-3” difference. Moved the rest a total of ¼ inch left of center shot again.
So, since lighter spine has same results, I switched the broadheads to see if that would change things.
1) Opened up a brand new box of 100 grain thunderheads and put them on the Maxima 250 arrows.
2) Reset my center shot
3) Field points dead on, BH 2-3” to right of field points again.
4) Moved my rest left 1/16 inch, no change in impact difference between BH and FP.
5) Continued to move rest in 1/16 increments to left, still no change in 2-3” difference. Moved the rest a total of ¼ inch left of center shot again.
I am lost here…don’t know what I am doing wrong or what it could be. Tonight, I am going to shoot my old bow (Darton Tempest Extreme) with the same arrows and broadheads used above to see if I get any different results with that bow.
Has anyone experienced this? Can anyone suggest something else for me to try?
