Arrows are "corkscrewing" - Help!
 

1st the Tech info:
Martin Jaguar Magnum
60Lbs
29" Draw
29 1/2" Easton 2315 xx78 w/ 4" Fletching
100gr Muzzy 4blade
(100gr Muzzy Practice Blades shoot the same)

I've noticed that my shots are doing a corkscrew like flight (clockwise)but are hitting accurately/consistantly for the most part. Once and a while I get a "flyer", but I'm consistantly grouping 3" at 30yds. The arrow flight is bothering me and I'm sure it's affecting my accuracy to some extent. Should I increase my broadhead weight to 125gr? Will this flatten out the trajectory? I've heard people discussing "overspined/ underspined" - could this be me? According to Easton's site, this is the correct arrow?!? Help me please.

NJB,

Did you papertest your bow? It can tell you of any tuneup problems.

The first thing I would think is a spine problem. Thats the most common tuneup problem. Is this fingers or release? Best way to tell if its a spine problem is to turn the bow down 2-3 turns. (If you have the space to do so.) Going to a larger broadhead will not help if its a spine and its effects on trajectory will be negative.

Usually the problem is one of either porpoising or fishtailing. This can be adjusted with the nocking point and/or arrow rest.

Lastly it could be a clearance problem. If the above doesn't fix this then spray the veins down with foot powder and shoot it. If it contacts something you will know where.


Two things for you. They will help you fix the problem and be resources for the future.

1. go to the Easton website and use the free download of the
Arrow Tuning and Maintenance Guide.
2. Ragsdale's Q&A is about the best thing I know of online for this

Yes this will affect accuracy. Also important is the energy loss you experience. Hope this helps.

Sorry for not being specific enough-

I'm shooting a center release w/ loop (d-loop?)that is permanantly attached to the serving around my nock point -- There are close up pictures on my link below if you have any interest in seeing the set-up.

Additionally, I've got a NAP quicktune 4000 drop away -- I have total clearance & am not rubbing the block.


Thanks for the insight.
