What is Your FOC?

Archer Dave · January 20, 2015, 02:54:00 PM

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!?

Archer Dave · January 20, 2015, 03:35:00 PM

Bisch - Thanks. I had been reading that anything over 15-20% was excessive. So this is not necessarily so?

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.

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.

Orion · January 20, 2015, 07:26:00 PM

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

Archer Dave · January 20, 2015, 07:57:00 PM

Thanks guys, I guess my FOC is cool then with the set up I am working on.

snowplow · January 20, 2015, 10:51:00 PM

Currently 28-30% depending on arrow

damascusdave · January 21, 2015, 03:41:00 AM

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

Troy D. Breeding · January 21, 2015, 07:55:00 AM

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.

sveltri · January 21, 2015, 10:42:00 AM

Right at 25%, CE Maxima RED cut to 30", 100gr brass insert, 250 VPA 2 blade.

Sapcut · January 21, 2015, 01:41:00 PM

830 grains, 32% FOC

DesertDude · January 22, 2015, 02:03:00 AM

650gr 29%foc
