I was curious what FOC you guys are using for whatever you shoot; i.e. target, roving, hunting.
I want to be set up for target and roving, but then be able to switch out to the same weight broadhead for hunting deer in the fall.
I am working on getting my new Grizzly 45# set up, and my FOC is 16% with full length (30" actual shaft 30.5" to nock point.) GT 3555 XT hunters using 3 4" trueflights and 125gr FP's at a total weight of 380.6gr.
I would like to up my arrow weight closer to 10gpp, but if I do that by a heavier insert or point then my FOC is going to be getting really high.
-So what am I to do?
-What do you guys do to get a lower FOC with a heavier arrow?
-What set up are you guys using and what FOC do you get with it?
Thanks,
Dave
High FOC is a good thing!
Great tuning is a great thing, regardless of FOC!
Great tuning and high FOC together is the best thing!
I have my bow set up for hunting, and I shoot everything with that same setup.
32" GT 55/75 XT Hunter black shaft
100gr brass insert
150gr point/broadhead
3-4" parabolic feathers
530ge total arrow weight
22.1% FOC

Who are you to ask such personal questions!?
Bisch - Thanks. I had been reading that anything over 15-20% was excessive. So this is not necessarily so?

I am me of course!
I shoot a 64# longbow with a very well tuned 350 spined arrow with 430 grains up front! My arrows weight 650 grains which is 10.15gpp for my bow and the Foc is at 32.5%! I have 235gr gizzly single bevel bh, 75gr steel adapter, 100gr brass insert and a 20gr footing on a full length victory hv shaft and 3-3" feathers. The main thing is a well tuned arrow, you can't get good penetration with a arrow that's not flying straight!
#65 longbow. 400 spine carbon, 160grain front and 530grain total arrow weight.
Foc 19%. 3x3" feathers.
My arrowed are tuned with 28.4% foc

I shoot anything from 15-20+% as long as it tunes for perfect flight and ends up minimum 9-10gpp.
That info on anything above 15-20% being excessive is horse puckey. Tuning is everything. I've had great arrow flight at as little as 12% FOC just as I have at 17, 20, 22% FOC, it all depends on if the arrow is right for the bow and what you're trying to do with it.
I use wood so not really into FOCing. I'm at 15-17% and about 12-13 gpp.
In wood, my arrows come out about where Bjorn's do. I like to shoot about 12 gpp out of my ACSs. In carbons, I build my arrows about the same weight, but get about 22-23% FOC.
28.5" ICS speed, 125 gr insert 250 gr point 2.5" vanes 705 gr 29.6 FOC. Use it for everything out of my 52# recurve or longbow
Thanks guys, I guess my FOC is cool then with the set up I am working on.
Currently 28-30% depending on arrow
My FOC varies between 10 and 20 percent I would guess...there are other factors that enter into creating an effective arrow that are just as important...my current elk hunting set up features a 900 grain total weight arrow with about 15 percent FOC...they shoot great for me

25% here with 11gpp, either victory vforce hv 350 with 350 up front, or gold tip velocity 340 with 300 up front, both full length out of 52# bows.
"So what am I to do?"
Raise your point weight to get to your desired 10gpp then bareshaft tune shortening arrow until she is right on. Higher foc won't hurt a thing
IMHO FOC is a personal thing. Some think it's hooie, others like myself believe in it fully.
55# bow shooting 705gr arrow with 34.4% FOC
I'm looking to get all the advantage I can, so added FOC is a bonus for me.
Right at 25%, CE Maxima RED cut to 30", 100gr brass insert, 250 VPA 2 blade.
830 grains, 32% FOC
650gr 29%foc
Thanks for all the FOC's. This would be an interesting thread to keep running and see what everyone is using.
20%
Let me preface this by saying that FOC is the last thing I worry about with respect to my arrows. I only know these numbers because at some point someone asked me and I checked. That being said:
Field and 3D arrows: 10%
Indoor target arrows: Not sure. I'll have to check.
Hunting arrows: 13%, and I've blown clean through every species I've hunted up to an including bull moose.
here's a post to show the real world advantages of weight and high foc. Things happen even on good shots.

Ben,
That's a cool thread, and I enjoyed reading it. But truth be known, that's nothing folks (myself included) haven't been doing with regular arrows for a long, long time.
