Range ball

first let me say that I test arrows that are by the charts suitable for the poundage that I am shooting.

I would imagine if you could get an aluminim 9/32 shaft the same stiffness as the arrows I shoot a heavier arrow would have good penetration values.
but larger diamiter shafts even if the spine is as stiff will not penetrate as deep as a smaller dia shaft because of friction.

speed is another factor that seems to be over looked concerning the lighter arrows

what you should keep in mind is that my current hunting arrow is traveling 350+ FPS off the string
and is traveling over 340 at 20 yards, speed does equal deeper penetration.

what I fail to understand why so many people are so bent to discredit this phenomenon without really examining it.

I have been a bow hunter over 30 years and trust me if I did not get such good results from shooting these arrows I certanly would not be using them!

I am not here to try to get people to change over to light weight arrows

i just want people not to be so quick to criticize something that they dont fully understand, I get so sick of the nay sayers who are totally ignorant to the concept, when I say ignorant I am not calling any one stupid but un willing to study the concept for them selves or un learned.
see what I am trying to say?

I remember when the 65precent let off bows were introduced, every one said it will never work now we have 80percent let off bows
if it was not for people thinking outside of the box we would all be shooting with flint broadheads tied to a stick and hand carved long bows.
people want more speed and the only way to achieve this is to shoot lighter arrows and like it or not that is the direction the industry is headed.
