arrow stability

[Zanda]

hi fellow archer's..

when I shot indoors at twenty yards, my arrows were very rarely straight in the target, they would be at an angle, left, right, up, down, whatever, but as I said raely straight....when I went outside and shot at thirty yards the arrows are now all straight, no sign of the of any deviation, so now I am wondering could it be that twenty yards wasn't enough time for the arrows to straighten out, and that thirty yards++ gives them the time they need.

your thought's are most welcome, and thank you to everyone who gives me help and suggestions on this one

Your ideas of extra distance helping to give arrows time to straighten makes sense to me. I've always thought that way.Some archers use big fletchings to straighten their arrows at short distances for that same reason.
There is another possibility. If the indoor target is straw and the outdoor one is foam, the straw can make arrows lie at odd angles to the target, because of the twists and windings.
Another thought on the same subject, would be to consider how well your arrows fly. If they are badly out of line at 20yds perhaps some tuning would help and check for arrow contact with the riser or rest; or even work on the technique.(I think I read that you were fairly new into archery)
I am not advocating changing your arrows, but it is possible that others could straighten more quickly. I borrowed a friend's arrows when I was a beginner and they flew far better than my own.
I hope this helps.
All the best

Thanks for that Geoff, the targets outside are the same as inside, so that would seem to discount the theory of different target materials. Flight wise they are flying well, so far as I can tell that is, my compound is wound upto around 54# and it doesnt leave much time for arrow spotting at twenty, or indeed thirty yards, however your comments are noted and maybe as I move the distances out, I might have chance to spot it, also will ask other members of the club their opinions, and will in due time let you know. Technique, well thats a good one I am still trying to replicate good form, on a repeatable shot by shot basis....lol cheers Geoff

Hi Zanda, I have seen the same thing though mainly with straw bosses, they can steer the arrow in at the last minute leaving it at a funny angle. It usually happens with ones that have been shot a bit and started to develop a few softer patches, it is probably magnified by the arrow flexing at close range, especially if you are shooting aluminiums with small to medium sized fletchings.

That said, I've seen footage of carbon/aluminium arrows still flexing all the way out to 90m, so I wouldn't be too concerned if you are getting good groups

Outdoors on a calm day, a good way to "see" arrow flight is with binoculars. You ask a fellow archer to stand well back, behind you, with the bins to watch the arrows exit the bow. Because he/she is well back, the first few wiggles can be seen,magnified in the bins. You need to choose someone who knows what to look for.
Good shooting

My guess is that you just need to do a bit of basic tuning. If the centreshot is off you'll see arrows misaligned left to right, and if the nocking point's at the wrong height it will effect them up and down. You'll notice it less outdoors because the fletching have time to do what they're supposed to do (i.e. stabilize the flight of the arrow).

I would doubt it would be flexing as many would shoot a similar setup and not have arrows steer into the boss, mine have only done it with a bad tune. Try doing a retune or try tuning for tens. I cant find the link so try typing it into google. But if they were grouping ok personally i wouldnt bother.

Here you go, walkback tuning

Maybe this will help.


Hang a weighted string from a nail on a target.

Stick a round sticker on the target face so that the string splits the sticker. Use your existing 20-yd pin, step back 20-yards from the target and fire at the sticker.

Don't worry about where the arrow hits.

Walk straight back to 30 yds, and using the same 20-yd pin setting,
fire an arrow at the sticker.

Repeat at 35 yds and at 40 yds, using the 20-yd pin and firing at the sticker.

If your arrows look like this pattern " / " or “\”,
then pick a direction and move your arrow rest 1/16th inch.



If the pattern gets straighter (more vertical), then that is great. Keep adjusting in that direction.



If the pattern gets more crooked, then adjust in the other direction.

Keep firing arrows and keep adjusting the arrow rest position until you get a vertical pattern of arrows.

Eventually, your arrows will hit in the target is a straight up and down line like this " | ".



LOCK down the arrow rest setting. Your centershot is perfect.



But, your vertical pattern of arrows may not be hitting the string.

The vertical pattern of arrows may be on one side of the string.
Let’s say the arrows are say 6-inches to the left of the weighted string.



Pick a direction to adjust your sight ring windage. Adjust the sight ring windage 1/16th of an inch. Repeat the test. Fire arrows at least 3 distances, and see if the vertical pattern of arrows gets closer to the string.

If the vertical pattern of arrows is getting closer to the string, then that is great. Keep adjusting in that direction. If the vertical pattern of arrows is getting farther away, then adjust in the other direction.

Eventually, you will have a vertical pattern of arrows right on top of the string.



Lock down the windage and lock down the arrow rest. Windage and center shot are now perfect.

thanks for that Gerry, its certainly something to think about
