Arrow consistency ?

[guam-bowhunter]

Today I was trying to tune my Allegiance and I notice something, and I'm wondering if I'm right about my findings.
I shoot at 70# with a 30" draw, 7595XT goldtips, 100gr. broads.
When I shoot, one arrow does not fly straight, it fishtails to the right but the other two fly perfect,so.....I checked for broadhead straightness and it was good so I tried switching broads around and the same arrow still fishtailed the same way, so I'm thinking, could it be a defect on spine consistency?

Another question, are aluminums more consistent? I was thinking of 2317's or2315's or what would you use for my set-up.

Thanks in advance for any advise.

Oh another thing I checked the whole arrow, fletches,inserts,nocks and everything looks o.k. even bent it back and forth just to check if it was cracked but it checked out.

Well if every things ok, it sounds like you have a bad one. Gold tip has some kind of guarantee. see if you can capitalize on it (let me know how it works out). Other than that there's only 2 things you can do with it. Either use it for target practice (since people are so fond of shooting their own equipment up) or put an L on the fletching where you will always see it and aim left.

guam, have you tried indexing the nock? not all arrows are semetrically spined. Twist the nock slightly, shoot and compare impact with the other arrows. Keep doing this a little at a time and see if the bad arrow starts to come in line with the others. the only other thing I can think of is the nock and or the inserts could be out of line. Hope this helps, Good luck GGBH

Guam, another thing, I always nock index tune my bare shafts before I fletch them. If I cant get them all to impact the same I take the bad ones back and exchange them. GGBH
