Tight groups..to the left at 40?

[1woolie89]

Hey guys I’m back again with a new problem occurring. Ok so paper tuned bow with new Hamskea rest. Got bullet holes at 3-10 yards, was drilling the target at 20-30 on a levelish area. Well I back up to 40yards up a slight hill. We’re taking a -7 degrees on the Range finder.
So I take some shots and I’m doing my best to have form/ relaxed wrist exc. Hinge release going off unknowingly and focusing on my aim and Sight level being in the middle. Well at 40 even with shots that feel good I’m stacking arrows, actually hitting eachother but to the left of the target 5 inches or so.
Driving me crazy trying to figure out what’s going on. Moving my rest did not help. Only thing I can think of is my 3rd axis? But at only a 7 degree would that even come into play? Appreciate the feedback.

3rd axis or unlevel bow would be my 2 cents??

Sight it in at 40. Then go back to 20 and see where it is. Things magnify at distance. Won't take much if an adjustment to bring it in at 40. Will likely still be on at 20.

That's the easy fix if it works. If not you'll likely need to shim or twist yokes depending on the bow.

And if your 40 is centered but your 20 is off, that will answer the question of 3rd axis.
It’ll help trouble shoot if nothing else, right?

I will and take some pictures of the before and after

Noting that I'm really inexperienced: I had a similar problem and worked out that I was slightly changing my facial pressure when shooting up hill and this was pushing my arrows the the left (I'm right handed).

 

[Planopurist]

I agree. Try third axis. If that’s fine, walk back tune.

see how it shoots @40 on a level area instead of the hill.....

Fast eddie XL and what housing? Double pin?

If using a multiple pin housing and you are still setting individual pins, they can be off a little on the vertical wire even tho it's hard to see.

If this is coming from a single or double pin then I'd agree it's your 3rd axis being out. Seems like it's a lot tho for 7degrees. I could see 6" at maybe 25-30 degrees shooting 40.

You moved your rest and that didn't help?????? Moving your rest will definitely move your arrows somewhere else depending on where you moved it. That might not be the fix, but the arrows definitely should have moved.

Set peep height at 40, Set all axis at FD.
Get zeroed at 40 yds.

Yeah I would agree not to move your rest just yet. First of all how are you setting your 3rd Axis? If it's not with a Hamskea level and a plumb line then it may be off slightly. Also what kind of impacts are you seeing with bare shafts and broadheads at 40?

I used the joint of my walls that well I’m assuming the contractor plumed correctly. Going to hang a plum line now to double check it.

I move it

1/8inc Twice and it didn’t seem to budge it over. Groups were tight though.
