Optimal grains per pound for whitetail?
 

Currently I shoot 9.4 grains per pound or something like that. I would like to go down, by a tremendous amount. Id like to stay with aluminum if at all possible. Whats a good hunting gr/lbs for whitetail?

RE: Optimal grains per pound for whitetail?
 

I'm not so sure I've ever read a grain per pound recommendation for whitetail as much as I have an overall weight of at least 400 grains total arrow weight no matter how few pounds you are pulling.

I've seen the thread over and over again through the years and the standard result is at least 400 grains is preferred by most for whitetails.

That is also the weight I strive to stay over.

I shoot 6.8gpp and it does just fine. arrow weight something like 420

RE: Optimal grains per pound for whitetail?
 

From personal experience I tend to prefer arrows weighing in between 6 and 7 grains per pound of draw weight. I think this provides a good compromise between a relatively flat trajectory and good KE/Momentum and penetration potential with a relatively quiet setup.

I agree with PA. I think 6.5 grains per pound is about the perfect balance of speed and penetration. JMO

DK 2312's would probably work for you pretty well. They will also hold up better than your 2117's. You would loose about 50 grains or so off you arrow which would bring you down to mid 8's for gpp. Couple that with swapping out your quickspins with Blazers or feathers and you will loose even more weight. With your wraps, blazers and a 125 grain tip you would be around 457 grainsTalk to Tom about it, he will give you some more ideas than I could. Just take off 25 more for the 100 grain tips you have now and you will be at 430ish. At least these are the numbers the computer is spitting at me

Right now my arrows are 420 grains which puts me at 6.46 gpp. As time goes on my hunting arrows keep getting heavier.

I shoot carbon arrows and have no problem blowing through deer. GPLB may not be the best indicator for proper arrow weight for deer. IMO KE is a better measurement, for example;

I shoot a 458g arrow @74lbs for pull. I'm shooting 6.189 GPLB. Another archer could be shooting a a 255g arrow @ 37 Lbs of pull and they'd be shooting 6.081 gplb. These two setups are very close as far gplb but not even on the same scale if you figured out the KE for both.

GpLB are great guidelines to go by for safe shooting and to reduce wear on your bow but the figures can be misleading when it comes to choosing an arrow for your set up.

For the compound I shoot 9 1/4 grains per pound, 2216 eastons.

On the longbow about 11 1/2 grains per pound, 2018 eastons.

Why would they hold up better? The 2312's have an extremely thin wall.

Probably because I was smoking crack BobCo... I meant to say that the xx78 2312's are a nicer arrow than the 2117 xx75's he is shooting.. I'll blame it on not being very awake when I typed it :D
