Question about broadhead tuning for serious bow shooters
Posted on 7/31/23 at 4:47 pm
Posted on 7/31/23 at 4:47 pm
I have a Mathews VXR and I just changed the strings/cables. I walk back tuned my field tips and they are pretty dead nut vertical. Now I am moving on to broadhead tuning and the BH’s are shooting 3-4” to the right of FP’s.
I have 2 questions;
Do you bring the field points to the broadheads or visa versa?
Would you make the adjustments with the rest or the top hats?
Some people say leave the rest at 13/16 and adjust with top hats but some also say use the rest. I’m leaning towards top hats.

Field points to broadheads
Top hats first = coarse tuning
Rest = fine tuning

Not sure if I qualify as a serious tuner but here’s my take.
Broadheads get moved to field point location.
Make small adjustments with rest 1/32 or 16th before adjusting cams or string twist. 1/32 or 16th of an inch movement can be a big change in POI but is not much from dead center of center shot.
How far is the target when you’re seeing the shift?
Also have you tried multiple arrow/broadhead combinations and seen the same results? I have chased a bad tune before that came out the be a bad head that was spinning right and appeared fine but was just a dud.

So far I have one response for chase FP and once response for chase BH
I am all within spec on DL, cam timing brace height and axle to axle. How exactly will a cable or string twist affect the broadhead planing?
For the broadhead tuning I was at 20 yards
No haven’t tried other heads. I’m wanting to tune my bow to the heads I’m shooting

Shot it through paper yet?
A perfectly tuned bow should shoot any broadhead or field point to same POI.

It shouldn’t. If the bow is in spec, move the broadheads to the field points with micro adjustments to the rest. I would paper tune first, that will probably fix it before you have to do much else. Shoot the same arrow several times and make sure you aren’t torquing it, get the same tear with the same arrow, get that same tear with all your arrows, and then get rid of it. The broadheads will hit the same after that.

Chris's Bee on YouTube did a video on this a couple of weeks ago. He did misspeak once and corrected his comment in the comments.
If the vert is good, move the rest slightly. Rest is fine tuning. Shitty top hat system is coarse tuning.

Shortening the cable affects cam lean and minutely adjust each fork of the limb. Same way that idler wheel adjustments add tension to the cables.
As for the head I’m not saying try a different style or brand just try a different one in the pack or a different arrow in and confirm it’s truly a bow tune issue and not a arrow/head combination issue.
For me i start with paper tune at 8-10 feet then paper 10-20ft then I shoot my field point at 20yd on a tape line then 30yd and adjust then 40then adjust rest . Then broadhead at 20 and adjust then 30 and adjust then 40 and adjust.
Paper is a starting point to which I start fine tuning and making very incremental adjustments.
Are you shooting helical ?

I had problems last year with BH/FP discrepancy. I setup new arrows after last season and bareshaft paper tuned them. They have been hitting together ever since. Might not be a bad idea to give it a try if all else fails.

Shoot a bare shaft at 10 yards. That will reveal anything a lot.

I didn’t realize how much conflicting information there was on group tuning online. Wish I still had my old NAP instructions because that worked for me the last time I had to do it.

I shot bare shafts through paper first before walk back tuning and got bullet holes after a few adjustments but paper tuning is just a starting point.
Broadhead tuning will reveal things paper will not because I’m shooting an 125 gr. fixed broadhead with a 1.5” cut.

Sounds like you got it all figured out man.
Posted on 7/31/23 at 9:45 pm to Jack Daniel
From Gold Tip: broadheads right of field tips
-Move rest to the right.
- Decrease load on cable guard (move cable guard towards arrow).
- Twist (L) yoke/ untwist (R) yoke.
- Move wheels left by changing spacing.

So I also shoot a VXR and have done I think every type of tuning discussed in this thread to that bow.
Here’s what worked for me:
1. Put rest in center shot. IIRC that is 13/16. You should ultimately land somewhere around there.
2. Paper tune as a starting point.
3. If bullet holes (like you said) shoot some bare shafts (with field tips on!!!) at 10 yards , likely will mimic your broadheads and be right of your fletched field tips.
4. Move rest TOWARD the broadhead or bareshaft. In your case move the rest right. Small increments, shoot and repeat.. (The bareshaft is showing you where the power stroke of the bow wants to go, you move the rest in that direction. )
5. If it takes more than 2/16 of an inch, meaning you end at 11/16 or less from riser, you won’t fix it with your rest.
6. At this point move it back to center shot 13/16 and start work on top hats. (This is what did it for me)
7. Look at your current top hat settings. You will need to slide the cams to the left. Easiest thing to do is to flip the top hats IF that will shift your cam to the left. Watch some videos on it. If that won’t work for you then order a set of top hats online. It’s not complicated but can get messed up if you don’t pay attention, they have to be matching sets. (I flipped mine around and it was money, I had already bought the set of top hats but didn’t need them) .
8. Shoot some more bare shafts and see what you got. Will take a little trial and error.
9. Move on to 20, 30, 40 yards with bareshafts.
10. Once you are out to 40 with a bareshaft hitting with your field points, your shite is dialed in.
11. Should be able to shoot just about any broadhead if your arrow weight/spine/fletching are appropriate.
I did this a year ago and I have broadheads and field points still together at 75 yards.
* I would not recommend messing with cables unless you have someone you really really trust working on it. Sammy at chags is the only guy I would let do that to my bow.
Also, be super careful with form when you shoot or you will end up chasing your tail like I did for a while.
Hope that helps.

Shoot Slick Trick broadheads
Posted on 8/1/23 at 5:30 am to tomcatrav
Tomcat has it pretty much nailed for the vxr. Twisting your cables and string isn’t gonna do anything for your nocks horizontal travel because the vxr doesn’t have yokes.
I would advise to forget about cam lean. My normal process is to check ata, brace height, poundage, and cam timing. Then I lay an arrow on the side of the cam opposite the cable guard and make sure they aren’t leaning too much and they are equal. On the vxr, they won’t be and once we started chasing that it never came together. We put it back to stock and adjusted tears with the rest. It never shot a perfect bullet hole but shoots broadheads and bareshafts pretty well.
I hate the top hats. But to tomcats point, once it’s dialed in, you may never have to mess with it again, they hold tune forever.

The top hat system is horrible. It’s setup this way to keep the avg bowhunter in the bowshop spending money on Mathews shite. Bow tech, pse, and a couple others have now made it possible to tune your bow without a press. Mathews needs to figure that out and a new adjustable mod system. But I doubt they want to.

Thanks Tomcat, very informative post.
I have a press at my house so I’ve tweaked the top hats before and I agree with y’all that this system isn’t the best. My Triax tuned perfectly but the VXR is giving me a harder time but this is the part I enjoy.
