Arrow wobble
 

I'm sure this has been covered a hundred times, but I notice a couple of my arrows wobbling in flight with broadheads when I shoot from about 25 yards. Can anyone help me figure out 1) why this is happening and 2) how to correct it? Is it a fletching issue? Spine? Weight? Tuning? Thanks in advance.

I shoot a Mission X4 at about 63#
Carbon Express cx300 arrows
100 grain g5 striker broadheads

I shoot an X3 and like it.

Anyway, there's no way to give you a definitive answer. I don't know anything about your arrow spine, but it could be part of the problem. Is there an on-line arrow selection chart by the manufacturer of those arrows? Your archery shop can check it for you too.

You say a couple arrows, maybe it is just those specific arrows? If not, it could be that you torque the grip every now and then.

After checking those issues, I would look to tuning. Always a good idea to get it tuned as well as it can be, even if you think they're flying OK.

RE: Arrow wobble
 

Number your arrows one through ??? whatever you got shoot them all in no specific order. If you see one wobbling immediately go see which one it is. Mark it down on little pad. If the same ones wobble I would keep them as practice arrows or at least check to see if it spins true. Could be a bad or misaligned insert or a bad arrow. I have had them with weak or stiffer spines...especially cheaper carbons. Now switch the BH's off the identified problem shafts and put them on another arrow. See if it starts wobbling consistently now. If so it is a BH issue. They can be machined crooked or bent!

If there doesn't seem to be a certain shaft or two then its tim to look at your form or a mechanical issue with the bow. Most likely its form (Choking the Bow with your left hand).

Anyway, give this a try and let us know what you find.

I had the wobble a couple weeks ago, and it turned out being fletching contact, stripped the Blazers instantly!

RE: Arrow wobble
 

All good advice here

fletch contact& spin test are pretty easy to check. Double check arrow spine with the charts.

RE: Arrow wobble
 

Your spine is too stiff!!!! Just guestimating, but punching your numbers into OT2, I get that you should be around a .425 spine, and you're at a .370 spine. A 250 would be a better spine for you and would fix you better arrow flight, just guessing that your DL is 28.5" and you arrows are the same, but tweaking the numbers every which way, you have a LOT of changing to do to get those 300 to be "right-spined" for your set-up. Upping your weight to 68# and a 125 gr head will get you closer. But really a 250 arrow would probably sync better with your set-up.

RE: Arrow wobble
 

When you say "fletching contact" what exactly does that mean? I have a whisker biscuit rest... I alsonoticed that several of my vanes look sort of wavy-- maybe that's part of the problem. I shot them all summer without replacing and maybe now is the time. Finally, would I be better off just getting a half dozen new arrows that are set up correctly for my bow? I think part of the problem is form-related, but I think partof it iseither a tuning or arrowissue.Thanks for all the help! I'm sort of new to this.

RE: Arrow wobble
 

Fletching contact is when your vane hits something on its way out of the bow such as the rest, the cables, shelf, etc...

I don't have much experience with the biscuit so i cant help ya there...

Getting some new arrows with good clean fletch catered towards your setup sure cant hurt!

RE: Arrow wobble
 

One more thing...

I was looking at Beman arrows-- the ics hunter or camo hunter. I read the chart, but, again, I'm kind of new at this and don't want to spend money on something that isn't conducive to my setup. So if my draw is 29" and I'm pulling about 63#, what length do I want my arrows and what is the correct spine? Thanks a ton again...

RE: Arrow wobble
 

The wavy vanes could be part of the cause, what type of vanes are you using??? Blazers are the best thing you can put through a biscuit from what I know, but that doesn't mean other vanes aren't "OK" as well, but most guys have better luck with blazers.

RE: Arrow wobble
 

The Plot Thickens!!!

All good information BrianK. Now that I know you have a WB and that you have wrinkled fletching that pretty well sums it up.

Is one certain fletch more messed up than the other 2on your arrows?
When you put your arrow on the string, where is your cock fletch? Striaight Up, Straight Down or Straight Out to the side? .... HINT: it needs to be straight up.

You probably have some tuning issues. I'd say you need to have your rest adjusted and nock set correctly.

If you don't want to buy new arrows you can save some money and turn your poundage down about 4 or 5 lbs. Also if your fletch are just wrinkled and not torn you can boil water on the stove and let it cool till it just stops boiling then grab all your arrows and hold them in your hand and place them fletch first into the water for a few seconds. Then lean them nock first (on the floor) and inserts up against a wall or whatever. This will help restraighten the fletch. Not perfect, but better. I
You can always have them refletched.
Either way, when you have the fletch issue straightened out, turn the nocks so that when the arrow is on the string the cock fletch (odd color one) is straight up.

If you buy new arrows be sure to adjust the nocks this way. You will still need to readjust the rest also. If you need help with this proess, I just spelled it all out in this thread....... http://www.huntingnet.com/forum/tm.aspx?m=2968982

Would you buy arrows from a bowshop or a mailorder house? If you will go to a shop (recommended) then take the bow, let them look it over, check poundage and recommend arrow size and length. Second have them turn the nocks for a WB and see if they can "Set your rest and square you bow"?

If you need help or have more ???'s feel free to ask.

RE: Arrow wobble
 

Our bows are identical, except for the riser color. My draw length is also 29", and I shoot a whisker biscuit.

My arrows are 27.5 inches long. At full draw I have about a 1/4 to 3/8 inch of arrow in front of the biscuit. At full draw, have someone mark one of your arrows whatever distance you want to have in front of your rest. Measure from the throat of the nock to the mark and that's the length of your arrow.

Easton's shaft selector indicates Beman ICSH/V 400s for 27 and 28 inch arrows.

RE: Arrow wobble
 

As for setting up your rest, most shops will set centershot by using some sort of guage. This won't work on an X4, in fact, you'll be quite a bit off. The manual states that centershot is at 13/16 out from the riser, as a starting point. This is measured to the center of the WB hole. You can do that yourself. You may find you need to make minor adjustments to find your centershot.

The WB should be set parallel to the string, as far as I know.

RE: Arrow wobble
 

This is all very helpful! Hey UncleNorby, what kind of vanes are you shooting? Also, Dryridge, thanks for the info about the cock fletch. I'm SOOOOO disappointed in the proshop that sold me this bow. I like the bow, but they never said one thing about the importance of getting the right arrows, I know it wasn't set up correctly when I bought it, generally they are **ckheads when I ask them questions, and the bow's max weight is too heavy for me. The reason I'm asking these questions here is because of bad experiences with the "pros." Thanks again, I'll take a look at all these responses, make some adjustments and let you know how it turns out.

RE: Arrow wobble
 

I shoot Easton aluminum 2315 arrows with the 4" vanes they came with. Not sure what brand easton uses.

If your bow is a 60-70 then I guess you can't lower it much, but if it's a 50-60 maxed out, you can lower the weight.

RE: Arrow wobble
 

Norby...those 2315 shoot good in any bow you stick them in. Iused to sell TONS of them.
That was until Carbons came out!

BrianK...I understand now. Sounds like UncleNorby knows more than I about your specific bow but if you need help with any tuning issues, I'd be glad to help anyway I can

RE: Arrow wobble
 

Hey UncleNorby,

When you say "centershot is at 13/16 out from the riser", do you mean from the "inside" of the riser? If so, mine is plenty off. Now, if I adjustit so that 13/16 is in the center of the biscuit hole, what is that going to do to my sight? Also, all of my cock fletches are set to the left and each vane to the right has black marks on it-- could that be because the arrows are coming in contact with something, the cable or whatever? And if I adjust my rest, could that help remedy the contact problem?

RE: Arrow wobble
 

Getting your Center-rest set right will help a LOT of things. As for looking for new arrows, check these out....

You'd want the 55/70's, but I've been shooting them for about 4yrs. now, and have been very happy with them. They are basically a re-badged Beman ICS Hunter for a little less $$$. And the marks certainly could be from the fletching contacting, the biscuit itself if you're that far out of center, or cables or whatever. Unfortunately, your "Pro" shop hasn't given you much assistance at all, but there are a lot of good minds to pick here that should be able to get you to the right point. As for the length of the arrows, I'm all for having a little extra arrow out there, and I draw a 29" bow and have my arrows cut at 29.5."

Good Luck getting everything set where you need it!!!

RE: Arrow wobble
 

Thanks a ton. I adjusted the rest and will be picking up some arrows today (from a different shop.) I'll have the shop check the poundage I'm drawing, the nock point, etc. and hopefully I'll eliminate that inconsistency and wobble with my broadheads. I'll let you know how it turns out.

RE: Arrow wobble
 

Yes, 13/16 from the inside of the riser. I'd imagine you are less than that now, so yes, you will have to adjust your sight. Moving your rest left (out) will make your arrows hit left. To bring them back in line you'll need to move your pins left.

WB's generally work best with cock feather up. Mine has black bristles at say 5 to 7 o'clock, and these are stiffer than the other bristles. They are meant to support the arrow. Tune your arrows so your cock feather is at 12 o'clock. The black marks are probably from cables, as this bow doesn't seem to have a whole lot of vane clearance even with the proper centershot adjustment. Could also be from the WB as your vanes are probably contacting the black bristles.

RE: Arrow wobble
 

Am new to site but thought I would add my recent experience.
I found the same thing with my bow after adding a new sight.
The cock vane (at 12 o'clock) was wrinkled, wavy, curly however you want to say it.
The pro shop sniffed it out immediately.
First problem: Nock was not set properly. Was too high which threw the arrow out incorrectly.
Second problem: My sight was mounted too low and the cock vane was rubbing the bottom of the sight every time.

They reset the nock and moved the sight up and problem solved!

They told me to spray the vanes with foot powder spray to see if there was any other places of contact.

Incidentally, I shoot with a fall away rest.

RE: Arrow wobble
 

One thing I have not seen mentioned yet is the effect of wind , it will make your arrows dance allso .
