arrow flight

[suro25]

If an arrow was under or over on the spine shaft would it effect the arrow flight?

Here is what I have going on.

equipment: Mathews Z7 draw length is 28In and draw weight is 63pounds. I have an ultra rest pro with Easton full metal Jackets (340 shafts)cut to 28inches.

The issue I am having is that the arrows are kicking with the nock end flying out to the left. I'm having issues with sporadic arrow flight.

For a righthanded shooter, typically, an arrow hitting nock-end left is acting too weak in the spine...for a lefty, nock-end left is too stiff.

I have close to the same set-up as you and shoot 400's with 100 gr. points.

The 340's shouldn't be too weak, so I'm perplexed...unless you've got fletch contact on the cables or rest.

You can try a heavier point, or up your bow's poundage...if the problem goes away, you'll know it is too stiff...or if the problem goes away by dropping the poundage / lighter point will mean too light in the spine.

Those are the two easiest things to try...first.

Then you'll want to look at your rest position, and bow tuning.

update:

I called easton today and said that my shaft selection was good for my bow but I might have to start looking at my rest. I might have a timing issue with my ultra rest pro.
