I am shooting Axis 340 (9.5gpi) 29" long, 100 grain brass inserts and 250 grain head.   I can shoot at 20 yards arrow flight is perfect, but when i get beyond 25 yards my arrow starts to wobble in flight just a bit.  How do i fix this, longer arrow, lighter tip, lighter insert, what do i do?            

I am shooting a Bob Lee Sig TD 59@28  62"

wobble in what way?  is it fish tailing, or porpusing or a combination of both?  Is it doing it with field tips or just braodheads?
Also are you shooting in doors when you see this?  Sometimes indoor lighting will give an optical illusion of bad arrow flight.

If your arrow flight is perfect at 20 yds and goes to pot at 25 yds then it is something in your shooting if I understand your post correctly.   :confused:      :confused:

Sounds to me that you becoming anxious at the longer distance therefore there may be some form deterioration at the longer distance.

Still not sure what you are trying to say.

the wobble is a small circle of nock in flight.  just with field tips and shooting outdoors.  havent shot BH yet, trying to find the right weight.  the reason i am leaning towards the 250 gr tip is there are a lot of glue on 125 grain heads that i can use with the 125 grain adapters.

I've noticed this sometimes myself, but not always.  I think it may just be wind deflection, more so with a high FOC arrow.  The hit where they should, but wobble around the nock.

Just a thought. It is a problem i had and was hard to detect and fix. At longer distance i had a problem with extending my draw lenght around 1/2 to 3/4 inch, the longer the distance the farther i would pull the bow.
once i fix it good arrow flight at long distance. Now if i could just hit somthing at long distance i would be good to go.

are the arrows hitting where you want them too?

Try Fletching a couple with all the same color fletching and see if you can still see it. May be the contrast of colors that you are noticing at longer range.

What BigRon said,this is why I shoot all same color feathers...

I will try the fletching, to see if that makes a difference.
thanks guys

I had the same thing Happening to the flight of my arrows with the very same set up on my arrows, bare shaft to 20 yrds great then start to wobble. I took the 250 grn points off, added rope inside the shaft went down to 145 gn points, now I can shoot the bare shaft to 55 yards and it hits the same place that the feathered shafts hit, I,m real happy with them now.

Also I might add that plastic tubes didn,t work well but the rope did the trick.

Dan, I also found that weight tubes werent the answer, but I havent tried the rope. Can you add a little more about that? What kind, what thickness, how long, how'd you secure it in the arrow, stuff like that?

too much weight?????? good luck...mc

Also Dan, does the rope make the arrow any quieter?

Russ I think the rope was 1/4 poly, cut flush to the back of arrow then pushed in with nock, and so far I haven,t lost any nocks and there is some noise but nothing like the tubes. My arrows are 300,s and weigh 630 grn and shooting them out of 68# longbow. and are flying good.

So how much weight do you think the rope added?

this sounds really good so far. Did you glue your nocks in, or just press em in there?

Russ, I just pressed them in, I have the weight written down at the house can,t remember off the top. the rope was twisted nylon that I picked up at wall mart. No more brass inserts for me, I,m going to .243 bullets behind the standard inserts alot cheaper.

Thanks Dan, I'm gonna try some of that rope I think.

I'll keep buying the inserts, way too lazy for what you're talking about. What do you do, glue or epoxy them onto the insert?
