Broad head tuning?

[sakoshooter]

I've gone thru a dozen a few times and every one shot exactly the same. Beman ICS Hunters in 340. Tried 400's too. Switched this year to Easton Axis 340's. They're shooting broadheads closer than the Bemans ever did and maybe right on based on my last few shots.

I find this quite common with carbon arrows.  I think fall away rests compound the issue a little bit as well.  It is my belief that the spine options with carbon are just too broad to accommodate every head, bow and archer as it was never an issue with all the aluminum spine choices.  I used to set my bow for middle poundage and adjust poundage up or down until I got the spine just right to group broadheads and field points.  It worked, but what a pain in the buttocks.  These days I use a micro gang adjustment sight and just count clicks.  I sight in for broadheads and then if I wish to shoot field points I have a click number written on the bow.  I move the sight a certain number of clicks left or right and field points are sighted in.  I never shoot fieldpoints during season so never a problem.

Radsav, what sight do you use?

Radsav,
That's pretty much what I've been doing the last couple years with my new setup. Micro adjustable but no clicks. I just make a small gang adjustment for broadheads realizing that my field pts will be off by a couple of inches. No problem during season.

That Eastman Tuning guide should really help get your bow tunes well. One thing it does not talk about is squaring the end of your arrow shafts. You can save a lot of arrows from the target arrow pile by doing this and increase you accuracy.

If you do a lot of shooting the ends of  your arrow shafts take a beating and loose the flat square shape. If you spin you arrows (with a broad head on ) and there is wobble it is most likely due to the shaft ends not being square. Use a squaring tool to get them as square as possible, you will see a major difference in how they spin and it will help bring those arrows together once your bow is fine tuned.

Use some common sense while tuning this way.  If you have to move the rest to a point your arrow is no where near center you've got some issues other than simple rest adjustment issues.  This technique is for arrows that are perfectly spined for the bow and using a bow with perfect cam timing.  These should be very minor adjustments.  If it seems like a lot you probably have other issues to deal with before using this technique.  When the bow and arrows are right it really is a great way to tune the bow.
