under spining
 

Is it best to be a lilittle over on your spine or over on the spine of your arrow.. I think I am a little under spining with the arrow and can't get a good shoot group... i just got a Nap qiuck tune 2000 and crack my Rapture up to 64 lbs and can't get a good shoot group... which arrows do I need?

RE: under spining
 

why not keep the arrows you have and drop the poundage a little?If in fact that is actually causing theproblem.

Slightly underspined arrows work well for target set ups sometimes, but not hunting. You would for sure be better off with a overly stiff arrow in a hunting set up with fixed blades. It would also up your weight some.

Having a stiffer arrow also helps with any inconsistancies from arrow to arrow in spine. If you have weak or border line arrows that have spine variances it will be much more promenent than it would be with a stiff arrow. At least that is what I have found.
