Trials and tribulations of broadhead sighting.....

[rob-c]

I would say you got it, now when you screw your  heads on your arrow spin them to see if the head wobbles in the shaft. if so, could be the head or the insert try swapping heads to different shafts to see if they spin true if the wobble..

So spin it between my hands like they r cold or praying? Look down at the head to look for off rotation?

Also noticed my practice head is not lined up with the vanes

yeah don't worry about lining heads with fletching that's old wives tale. google diy arrow spinner, there's some neat ideas , you want to spin the arrow so you can see if the head wobbles on the axis as the arrow is spinning. think how a foot ball will fly nice and straight with a tight spiral and if it wobbles its wonky in flight .  you could try in your hands but the arrow needs to be stable and not move so you can see the wobble. wish you lived closer I could help you out I see your in central ny I am in southern tier.

Simple project. I'll get the stuff to diy one next time I'm out.

Got out today with a buddy. Hitting 6inch groups at 40. All around the boiler. At that distance I'm wishing my pins were smaller and less cluttered. At 30 groups are 2 inches. Fields and broadheads.

I don't think the bow is 100% tuned as when I first went to 40 all shots were way left. Made a micro windage adjustment on the sight and brought 40 yards inline.

And 2 arrows still don't fly right. I'm going to have to break out the scale and diy that roller to see what the issue is.

Well thats pretty good shooting. the two arrows that are still not grouping try this , take your nock and give them a 1/8 to 1/4 inch turn inside your shafts at a time ( if you can with out hitting your fletching) and see if this brings the two arrows in. It may be a slight spine issue with the two, and if you can't and have enough to hunt and practice with then call it good .

I have to do this.  Lucky for me I have a guy at Suffolk Archers Wai who helps me tune the bow.  We usually paper tune, I do a 60 yard shot to see if the pins line up and retest at 20 if they do I then set up the broadheads.  Hope I can get it done in one day!

Alright. I'm giving up. I don't know if I've just been shooting so much that I'm losing it. Or if the bow is still out of whack.

Stepped out for a couple arrows.

1 FP hit bull. 1 way low the other way left.

Shot BHs. Both 2 in grp on bull at 30 yards. A fourth FP hit bull on a different target.

I noticed that the ones that were off flew awkwardly. Is it possible that all the abuse these arrows have taken has warped them and it's just not noticeable without a spinner?

At any rate the BHs are consistent. (2 of them) so I'm not messing with the bow adjustment anymore. I'm going to just practice a couple shots a day focusing on form. Until season.

As I was asked in a different thread and then checked. Is everything tuned up and level? You are shooting more then one broadhead at the same spot on your target. That will zip off the vanes, and even maybe put small cuts or abrasions on the shafts. Shoot one broadhead to one dot on the target. Some might disagree, but it will save you some headaches.

As tuned as it's gonna be for a day or two went through leveling and paper tuning this weekend

Noticed you mentioned moving pins to poi, that's not going to help you tune as your BHs and FPs  will still hit in the same pattern, just at a different spot. 

You should be moving your rest or rest/plunger to get BH and FP to same POI, THEN move your sights to slide POI to bullseye .  Paper tuning is great but only tells half the story, try a "walk-back test" or follow the easton guide pinned to the top of the bow hunting section, awesome resource and the moderators are brilliant for posting it.

fliers more likely due to spine alignment issue, try rotating nocks as mentioned above.  You may also be getting some vane contact with the rest, try spraying vanes with aerosol foot powder, shot the arrows and look for streaks in the powder.  If neither of those work or give an indication, it's probably a form or concentration issue that shows up once in set...for me, it usually indicates that I'm getting too confident in my abilities.  The only way to know for sure is number your arrows on a vane and if the same arrow keeps flying to the same spot, different from the others, it's the arrow.

I'd wait till you get your new arrows before you get to frustrated they will tune different...

I warned you that you would get very mad I also warned you about over shooting because form would go to hell. Take a couple days off and give it another whirl. It will be worth it trust me! I would never step into the woods without a bow that is perfectly tuned for reasons I stated earlier. Hunting with a bow that isn't tuned is like hunting with a loose scope mount. You will never know for sure where it will land.

Buck!!! I've been waiting for your insight.

I ordered some stiffer arrows as the tears I got were possibly due to weak spine.... I'll update when they come in.

What arrow are you shooting now? What's your draw weight and length and bow?

I haven't read through this whole thing, but have you gone to a pro shop?

He is paper tuning, why would anyone pay someone to tune a bow?

I initially took the bow to a pro shop. Had them tune the new rest I bought there. Check timing and check string. Max bow poundage. Check cam integrity.

Shooting 50lb draw. 100g heads. 0.4 spine arrows. Draw length 30. Arrow length 31 1/2 at 380grains total assembled weight.

I appreciate the advice and comments from everyone. Once the new arrows come in I'll do a new thread with less.clutter.

The 30 inch draw is what threw the original arrow selection off, once you get longer draw length the charts are deceiving or plain wrong. I went through this a few years ago and had to go to a spine stiffer than the chart recommended. It solved all problems.

There are other work around's in this situation such as a lighter BH/FP or lowering poundage and even taking a half inch off the arrow would help. The easiest is to go with a heavier spine though.

because he seems to be at a loss at this point? the comment about not being sure if his arrows are properly spined? at a certain point I would think spending a few bucks for help is cheaper then chasing accessories that may or may not be the problem. The pro shop I go to helps out their customers for free most of the time, could very well be a very simple or cheap solution to the problem.

There is no mystery here, it is a weak spine. No need to complicate things with archery, if tuning doesn't yield results there is something wrong with the set up ie arrows, rest, knocking point.

[Buckmaster7600]

If your draw is 30" I highly recommend going up a spine from what a chart says. I have a 31" draw and I have to do the same thing.

I looked at CE's chart and it calls for a .350 spine for Zeus's set up.

 

 

[zeus1gdsm]

I went with carbon express whitetails in 350 or. 0.339. Im hoping the drop from. 0.4 will be enough to correct the flight/tuneing issues.

Also grabbed a pine Ridge arrow spinner. I looked up diy jobs and they didn't seem to spin very fluidly. Then looked at the bearing diy options. Which puts you in the pine Ridge price range
