Fletcher- your response gets sort of to the heart of my question: do we begin with point weight and then deal with arrow spine (the 3rivers spine chart to function this way)? Or do we start with bow weight, pick a spine, then worry about point? I'm beginning to see that I need to almost think about what weight point and go from there. Thanks for everyone's response!!

You can go either way. I have a lot of money invested in German Kinetic broadheads, so I always start with a known head weight and work from there.

If you already have a bunch of arrows and not broadheads, then you could mess with point weight till you get it right. Then go buy broadheads that match closely what tuned in correctly.

I have to ask, why is 10gpp. seem to be the magic number? Shot a ton of deer shooting between 8-9gpp at weight from 42#s to 85#s and the deer never noticed. I think people get way to caught up in arrow  weight, the priority should be to put it where ya want it and tune the arrow to fly perfectly, if you end up at 8gpp or 15 gpp. it makes no difference. Now Moose and some thick skinned critters it does but whitetail none. I myself shot the full length of a coyote and a big doe a few years back, shooting 40#s at 28.5"s and arrow weighed 312 grains.

I don't know carbons from corn, but with wood shafts, I pick my broadhead weight and arrow length and paper tune with test arrows to find the spine I need for a particular bow.  I then pick shafts of the spine and weight to give me the finished arrow I want.  Because woods come in all spines and weights, this system works very well.

10gpp is not a steadfast rule! It is a general good place to be. I would much rather have a well tuned 8gpp arrow than a badly tuned 10gpp arrow. That being said, a heavier arrow will penetrate better, esp when bones or the like are encountered. I also say "use what works for you". If you got a setup that you have proven to yourself works, by all means, go with it. If someone asks for advice on what they should use, I will recommend a bit heavier arrow.

At the end of the day, it is (most of the times) shot placement that determines whether a successful recovery will be made.

125 or 130 gr on wood shafts.  My all-up weight goes between 520 for cedars to 600 for Douglas fir.  10 or 11 gpp.  They go through whitetails nicely.

All my bows seem to end up with tips and broadheads between 150 and 200 grains depending on the bow and arrow combo for the day.  Never had a problem with whitetails.

Usually shooting 150gr. broadheads with 100gr. brass inserts behind them in my carbon arrows. Has been a very successful setup for me.

Hey all! Just wondering what weight broadheads guys are using for whitetails? My bow at my draw length shoots about 50# and I'm wondering if it would beneficial to load the front-end of the arrow with some good weight. I'm looking at going with carbon arrows. Anybody know enough arrow "theory" to help me select what would be best in terms of grains? The way I'm looking at it is like this: if I use a lighter carbon arrow I should probably have some weight out front to help with penetration. Am I right on this? Thanks!

I shoot 50lb recurves. My setup is 30" easton legacy 2016, 145 grain stos. I think im around 9-10 gpp. No problem with penetration here! I also used to shoot high FOC carbons but for NA animals I'm not sure it makes much difference. Nothing wrong with it either if that's the route you want to go

I typically use a point weight from 150 grains to 200 grains in front of a 100 grain brass insert on all my carbon arrows. I really want my arrow weight over 600 grains in case of bone contact, and this much foc really does make a difference in penetration.
