Title: corkscrew arrows?
Post by: team fudd on September 21, 2011, 03:18:00 PM
Thanks in advance for any advice you may have.  I have spent the last two years honing my skills and have gotten to the point where I am relatively satisfied with my accuracy,  I have a repeatable shot sequence and except for a very occasional flyer the arrows go where I would like them to.  (for the most part)  However,  I have noticed here the last few weeks that every once in a while I get an arrow, or a couple arrows, that I can see "corkscrew" in flight.  they dont look nock high,low,left, right,  they look like they are literally corkscrewing through the air.  I shoot a twenty eight to twenty eight and a half inch draw.  carbon express one fifty with weight tubes and 125 grain point. total arrow weight is around 580 gr.  I am shooting apprx 53-54lbs out of my longbow.  Any help would be greatly appreciated.

Have you tried bare shaft tuning your arrows to your bow?

Have you tried marking all your arrows, so you can see if it is one particular arrow that might be causing the problem?

String may have stretched beyond tolerances for your arrow spine.  Try raising your brace height.

Nock point may have moved.

You draw length may have shortened unknowingly to you and your arrows are too stiff for that shorter draw length.

Thanks for the suggestions,  The shafts were tuned to the bow over a year ago and I am just now seeing this corkscrew effect.  I will take all suggestions into consideration and see what I can come up with.  Archery deer opener is saturday so I better get on the stick!

thanks terry,  it appears in my efforts to quiet the bow down I got the brace height a little too high. brought it back down a quarter inch and we are good.  Ready for saturday!  Sharpening broadheads now!
