Title: Extreme FOC?
Post by: Gator1 on August 06, 2009, 06:01:00 PM
I was going to tune a Blackhawk Vapor that is I believe 6.7 Grains an inch.

30" arrow, with a total of insert and head of 250 grains.

Is this too extreme F.O.C.???

Thank you,

If it will tune to the bow it is fine.

I like 200-225 grains on my Beman or Axis arrows.

I shoot Beman MFX 500's 30 3/8" in length with two 100 gr. brass inserts and 145 gr. field pts. fletched with 3 five in. feathers, total weight 655 grains. they bare shaft then paper tune beautifully out of my 54# @29" 62" Toelke Whips. F.O.C. is 23-24% but I shoot them because they fly so well, chronograph at 168 f.p.s., are ridiculously quiet and penetrate like crazy.

I'm planning on building my Gold Tips the same way, if the brass inserts ever get here...PR

I have 300 up front (125 head, 75 grn adapter, 100grn bass insert) on 29.5in beman mfx500's ... Fly great quietly out of a 57# toelke whip!!

Overkill for whitetails, but if I run into Hogzilla...I should be able to get er done... Real quiet as well

I had worried that my set-up wasn't properly spined !!! Well, I thought they flew well.. But looking that I am close to Bob's set-up.. I guess i did do it right!!!

I always look at it like this.....

If you pick your desired tip weight, you can build an arrow backwards to tune to your bow.  If you start with an existing arrow choice, though......you can't (most likely).

As was said before....if it'll tune to your bow, you're golden.

I've been shooting 55-75 GTs cut to 28.5 with 100gr brass insert, 100gr steel adaptor and 190gr grizzly BH (total arrow 646 grains, FOC 28%) from my 52# @27" Liberty Elite. They fly very well with 3 4" feathers so I think they will be my elk outfit this year.  The really great advantage of the high FOC is that they don't take much feather to fly well if they are tuned right.

Ive got Carbon Express 350 Heritage at 28" with 8 gpi weight tubes, and Simmons 190gr Interceptors...Total arrow weight 725 grains...My FOC is only 14.29%...Im shooting a John Stadler custom recurve 62", 70#@28".  This is my first year hunting with a recurve...As of now, these are shooting like darts but the setup is unproven to me on game...What do you pro's think?  Should I add more weight up front and try to tune it for a greater FOC?  Thanks

Shooting 70lbs any arrow you shoot will kill anything in Alabama. :)  Your setup is fine like it is.

What James said, unless they have opened the season for wooly mammoth in Alabamer.

LOL....It may be a little over kill but it shoots really well...Like I said, it's my first recurve and Im new to traditional archery...Ive been shooting the one with cams for about 20 years and that made me a better hunter...I just thought it was time to step it up a notch...It's not how far you can shoot, it's how close you can get...I appreciate the advice...No wooly mammoth over here in Bama but the hogs are getting prety wooly....

Did not mean any disrespect Longshooter 70. With your set up and a sharp well placed broadhead, you won't have any problems.

Absolutely did not take it that way....If we all had a little better sense of humor, the world would be a better place....Hold em hard...Shoot for the center....

One of my best setups right is a 31-1/4" 340 gold tip with a 100 gn brassy and a 200 grain tip or broadhead. Was bare shafting at 45 yards with a field tip on a SAIII 60" 55@30lb bow the other day (it will do it at 65 yards too). Total weight is over 600 gn.
Have a 38lb Morrison ILF longbow that is shooting a 32" 400 with 200gn up front. Total weight is 480 grains. This set-up would bare shaft well too. This arrow/bow combo is gaping at 60 yards split finger with a 12 grains per pound arrow.

I built a set of Gold Tips for an upcoming moose hunt.They are 394 grs up front,using a KME modified Grizzly El Grande,709 grs total and the FOC is 28%.Non scientific tests show them penetrating double what last year's normal FOC arrows do off the same bow.

I'm kind of in Georges' camp now after some stumping and a lot of field archery outdoors. I noticed some really bad trajectories stumping with super heavy arrows with my heavy pronghorn. I've backed off from the really high FOCs and just front load to at least 19% and not much more than 22 or 23%. I can still get the extreme advantages of EFOC and keep the arrow speed up with a decent trajectory. Remember what Ashby said; true arrow flight is one of the most important factors of penetration. I doesn't hurt to cut the feather off of the quills on one of your hunting arrows to see how it really is flying. Extreme FOC tends to help arrows recover from spine issues very fast.   Just some things to think about.

I have been happy with FOC from 17-20, but over that I don't like the all around arrow performance.  I hunt deer so I don't see an real need for anything more.

When bare shafting a very heavy FOC arrow, doesn't it show extreme nock high?
Title: Re: Extreme FOC?
Post by: katman on August 18, 2009, 09:27:00 PM
David, NO it does not. It is a fallacy that efoc nosedive! If the total arrow weight is very high you will see a lot of drop, especially past 25 yards, but that is due to the TOTAL arrow weight. Like I posted I'm shooting 25% foc with 10 gpp arrows, good trajectory, penetrate well and bare shaft wonderfully out to 25 yards without nosediving.
