I am fairly new to bowhunting and have a question. I shoot my bow about every other day to get ready for bow season to open and I noticed past 15 yards that the tail end of my arrow seems to make a circle as it flies (it makes a cone shape with the tip being the top of a cone). Is this a problem with the straightness of the arrow or the vanes?

The bow is out of tune. You need to head to your pro shop and have centershot checked, and check your arrow to see that it's level on the rest.

It may be partially due to a spine issue, but mostly your bow is just out of tune.

I agree with mobow, your bow is out of tune and you maybe underspined/overspined as well. Head to the proshop and also pick yourself up a good bow square and learn how to check these things on your own incase you run into problems in the field. They are pretty simple to use and relativly easy to learn how to make sure everything is square and in tune. I bought one a couple years ago andI tell you, it has saved me a little cash. I think most will agree on having a bow square on hand. They are pretty cheap. Get the NAP kit with the square, knocking pliers and knock points. But i really dont think its your arrows. What weight arrows are you using and what poundage are you drawing? Also what weight head are you using.

I am using a 100 grain tip, draw weight is 62 lbs, and my arrow weight is 2 grains

2 grains ?

I don't think so.

All of your arrows or just some? Could be an arrow problem as well. Or a nock problem.

I have never had an out of tune bow spiral arrows unless maybe there was severe fletching contact or something. Fishtailing yes, spiraling not so much. Normally when I see that it is a bad arrow, damaged nock or messed up fletchings.

Number your arrows and see if they all do it, or just some. Being really weak on spine might cause it too.

Just my take on it anyway.

2 grains????
better weigh that again on a different scale? If its true im suprised your arrow flies at all...I think a 2 grain arrow would explode on release.......correct me if im wrong someone.....but isnt that like almost as light as a feather?

I think that's lighter than a feather actually. I am sure he just isn't up on archery terminology. It's painfully obvious that his arrow doesn't weigh 2 grains.

It would be better if you told us the make and model of the arrow you are using. Along with the size that is printed on the side of the shaft and how long it is from one end of the shaft to the other. Not how long it is with the tip in it, but from shaft end to shaft end.

The actual weight of your arrow really isn't that important, although a heavier arrow would be more stable in the wind. How much weight you have in the front of the arrow might make a difference though (FOC). An extremely low FOC arrow would not stabilize very well.

haha yea i messed up... as paul said im not familiar with the terminology yet, but my arrow says (weight tol. +- 2 grains) but the shaft weight is 233.7 grains... sorry guys
