Arrows showing weak regardless of point weight

[Lakerat007]

Put a flipper rest on it and call it a day. I enjoy shooting off the shelf but when tuning gets to be a pita the flipper is getting slapped on. Convinced I could shoot rebar of a flipper with no probs.

I understand you wanting to get everything perfect, the game we hunt deserves as much.  In your original post in number 4 you said fletched arrows were hitting where you were looking. Put the broadheads on them that you want to hunt with and shoot them from 10 yards if they are still hitting where you are looking and going into the target straight move to 20 if you are still hitting where you are looking you are done go sharpen your broadheads. We don't hunt with bareshafts there is a reason we put fletchings on them. If fletching want correct the problem the spine is way off. I hope this post does not come off as being smart I don't mean it to be. Good hunting Jimmy

On the surface they seem overspined.
I'm using .340 Eastons with 2 inches of alloy footing, 100gr. insert, 125gr. broadhead adapter, 200gr. broadhead out of a 68lb longbow and they're full-length! I know every situation is different but they're tuned bloody well.

I think you need a 340 spine.
