Broadhead tuning

[2brassballs]

Hey guys need some help here
I broadhead running my new Elite 35 and my broadheads are dead on at 20-60 yards but my fieldtips are shooting way to the right.
What should I do?? Any help is appreciated

So the broadhead are impacting to the left of the field points.

First and this will be controversial...you can just leave it sighted in for POI with the broadhead and not worry about the field points.

Or a better alternative is to have both hitting the same poi.
Too do that assuming your right handed would be to nudge the rest towards the bow in very very small increments ....till they have the same POI and then readjust your sight.

Walk back tune your bow. Lost of videos on you tube.

where is your centershot at? and is this a right handed bow?

 

[2brassballs]

Boom I don't know what a centershot is??
It is a right handed bow 29 inch draw 84 pounds
Archerm I've done it 20 to 30 to 40 to 50 and 60
At 20 I'm 4" to right
At 30-6" to right
At 40 -7" to right
At 50-8" to right
At 60-10" to right
Virtically I'm there 2.5 groups at 50-60 yards

He is asking what is the measurement of your center shot. Take a tape measure and measure from the riser to the center of the arrow and report back. For example, Hoyts like 13/16 and 3/4 for the most part. BTW, did you paper tune your bow (as a start) and then walk back tune from there?

84 lbs...you must have two brass balls! What arrow spine are you using?
If spine is correct, draw length is proper and cams are timed. Set centershot as others have mentioned and then move your rest horizontally chasing FP groups with broadheads, if this doesn't bring groups together do the opposite and chase BH with FP.
If after attempting this and you can't get them together try setting your rest at centershot again and modifying your grip.
Since you don't have a yoke system to play with grip changes may be required. I also shoot a binary cam like your elite and have found that to get BH and FP together I changed my grip to have more thumb pressure.
Ontarget7 (member of this site) has some really good posts over on archerytalk using Levi Morgan's grip as an example. I found these super helpful.

What arrows are you shooting.....model and spine? What other arrow specs do you have? Length, vanes, total weight, BH's used?

You could probably tune with 300's but a .250 spine would be better, possibly even .200's.

Jeff Martin - no I have not paper tuned my bow shop that set up my bow for me laser tuned it and I been shooting it for past 3 months with out any issues I shoot weekly out to 80 yards..
I'm shooting a Easton deep six 330 spine
460 grain 2 " blazer
I been shooting 80 pounds + for last 10 years.
Thank you for all the help

Centar shot is 17" and I'm shooting slick trick magnum 100 grain deep six

Center shot is measured from riser to center of arrow like this:

 

[Brodie]

With 84lbs at 29" you are underspined with the 330s
Also centershot is the measurement from the side of the riser to the center of your arrow on the rest, like others have said it should somewhere between 3/4-7/8"
Try googling the "nuts and bolts guide to archery". It's a pdf with lots of good info that will explain/have diagrams for some of the measurements and terminology.

 

[William Hanson (live2hunt)]

Nuts and bolts tuning guide is invaluable but a bit overwhelming.

Here's a thread I started with some good info

The 330's could be most of the problem. I shoot at 32 1/2" draw and with 340's things go haywire at about 62-63lbs of draw weight. At your 29" draw length that would equate to about 79.5lbs of draw weight. I would bet that a stiffer spine would mostly fix the problem.

 

[boom]

Wow.!!!! I had no idea an E35 had available 80 lb limbs!

Badass. My e35 is at 67. Hehe. Need to twist some cables but it's shooting so dang good...... I'm leaving it.

My center shot is 13/16th.

I think your arrows are two weak. Try moving the rest a tiny bit to the right? Or back off limbs and see if it gets better?

I'm by no means a tuning pro, but I paper tuned my Matthews, my dads Matthews, my wife's diamond infinite edge, and my sister's infinite edge...

Just by working up so I got a good paper tear on each bow made it so broadheads were impacting within an inch or so on each bow as long as the shooter is careful to not torque their wrist etc.

Broadheads in use are: Montecs, G5 Strikers, Shuttle T's, and Muzzy

Sounds like you are shooting a week spine too tho, so start there perhaps... paper tuning can verify a weak spine as well.

Thanks guys for all your help I will try

I wouldn't recommend changing your grip at this time of the year. You don't have enough time prior to the season to make the change. It may help you in the yard and get things squared away. A month from now when you have the adrenaline rushing and are not methodically thinking about a shot your grip will revert back to what you had always done and your shot will be off.

That is a project to start working on in December, not September.

I'm not sure what changed tonight but I had great groupings out to 60 yards..
I shoot 6 arrows at 20,30,40,50 and 60 and had only 1 arrow outside my 6" paper plate .. No changes were made to my set up I was more relaxed and not as sore tonight. Let's see what tomorrow brings. Thanks again for all your help guy
