How Many GPP

What is your favorite arrow weight for hunting,measured in grains per pound of bow weight(GPP).Please no debate,it's just a poll to see what you like.

Do to my disdain for applying 10 gpp as a general guideline, I am hesitant to vote.
The general 10 gpp guide line today is possibly an all around great choice for further ensuring possibly greater efficiency, enhanced safety for the bow and the user itself. Of course there are exceptions. I firmly believe the gpp guideline evolved from an era in the years when higher poundage bows were the norm.
Just concerned that the poll results could negatively promote using gpp arrows that do not take into account the all important factors of draw wt, arrow design, intended game and having over-all set-ups designed for the unexpected vs. requiring a virtual perfect mark. The results so far contradict the useage of low gpp of which I am well pleased and feel more secure for both the protection and longevity of our traditional community and the beloved animals we pursue.

For deer sized game:
Draw wt. - Mid to Low 50’s
Over-all efficient arrow design(~30% Ultra-EFOC)

I choose the 10 - 11 gpp range

Mine worked out to 11.2 gpp, but that's just coincedence.  I shoot Douglas fir, 12" rear taper and 130 gr broadheads with 1/2" knuckle/riser clearance at full draw.  No idea what the FOC works out to and gpp is secondary to good flight and good penetration.

I can't vote in this poll.      :(    

I have two bows which you can see in my signature. One shoots a 10.02 GPP arrow and the other shoots a 11.37 GPP arrow.

There isn't an option for me since I can only choose one box and I need two boxes since both arrows fall into two separate GPP categories.

I'm pretty sure it came from Fred Bear and Howard Hill in the early 40's.. Fred did a lot of testing with different weight arrows and how hard they hit about '43 if I remember what I read when I was a kid.. the most common draw weight back then was 45-55 pounds..

I didn't vote either. I let my bows dictate what they want. But I try, repeat try, to stay above 8gpp, but have and will go below for the needs of the pursuit. (low pound bows vs. squirrel = need for a fast arrow. Dang jummpy creatures)  :mad:

Shaping up quite different than the poll results taken on 6/29/2010. I believe the differences, in part, reflect a more informed community.

I'm with Friend for the most part.  I don't think GPP is a good measure unless you stick to a very narrow range of bow weights.  

With a low weight bow, say 40lbs, you need a higher GPP to try and preserve all the momentum you can.  With a higherweight bow, say 75lbs, keeping every slug is not as critical, so you can get away with a wider range of GPP.

I start at around 450 grains of arrow for a 40 pund bow and add 50 grains every ten pounds or so of bow weight.  Makes a lot more sense than saying a 450 grain arrow will work out of a 45 pound bow but isn't going to penetrate out of a 55 pound bow.
