Is 8.6 gr/ per inch enough arrow weight?  I know more is better on tugh game, but that is what tunes best out of my set up?   55 lbs @ 29 draw / 475 gr arrow?  140 gr. up front...  

For whitetail deer / maybe a pig or two! hahah

Most Bowyers recommend at least 10 or they won't warranty the bow. What arrow are you shooting and how long?

It's enough for a whitetail and what tunes best is more important than a few grains. Most bowyers put the threshold at 8gpp that I know of.

I agree with Dave...My bow warrenty require 8 gr minimum

It should be just fine for whitetails and pigs.  Good luck.

Works for me with similar # and draw. Been using that type of arrow to bow weight for 10 years with no problems.

Steve,

I assume that you meant 8.6 grains per pound of draw weight and per inch. It if shoots fine out of your bow use it.

I would check with your bowyer to see if he has any minimum gpp standard and then see if you care or not.

If your bow is kind of loud, then a heavier shaft and a heavier head to compensate for the extra stiffness will likely make it quieter since it will absorb more of the excess energy that is making the noise.

I don't consider 475 grains light. That's a pretty ample arrow for any North American game, as long as it is flying perfectly.

This grains per pound thing is too ambiguous and subjective.  Bow noise can be lots of things too, including tight nocks, improper brace, weak or stiff spine, etc.    I can tune my bow to shoot a lot of different weight arrows without significant noise issues.

Fine. I wouldn't buy a bow that wouldn't be covered for 8.

I agree with my old buddy Curveman- my setup for this season is a 71# Super Kodiak, 1970 model and a 630 grain 2219 arrow. That's only 8.87 grns. per pound even though its a pretty hefty arrow. Paul Shafer shot 2219s out of 90# bows. You should be fine with this setup. Like George said, if its flying really well that will beat 10-11 grn. per lb. flying poorly. Might want to up it a bit for elephant or cape buff though. Grant

No plans for cape buff. or elephants. There aren't to many in the swamps of Louisiana. hahah... Thanks fellas... Steve

My arrows are beman ics hunter 400 spine 8.4 grn per inch with 200 tips up front 30 inch total lenth, total arrow weight 480 grns and they shoot great. Monday I shot a doe with these arrows but only 100 grns up front (couldn't wait for my inserts, bow hand was itchy    :D    ) That arrow weight should be fine, as long as you dont have  a warrenty to think about, I shoot 51# @28 and pull 29" (that gives me 8.8 grains per pound)
