I’m sure there are more folks out there trying for high FOC than there are posting around here. I’m interested in knowing how your results are coming. Don’t be bashful, this will tell me how many really except this style of arrow. I’m not trying to make this into a bragfest or anything. However, if your results aren’t up to par this may be your chance to learn afew things. If your results are exceeding the average I’d like to know. I interested in any results.
I’m using .320 deflection shafts with 100gr brass inserts, 315gr points, 35grs of exterional footing and three 3″ A&A style feathers. So far my best to date is 33.04% with fieldpoint, but when I screw in my broadhead it jumps to 33.46%. Weight of the finished arrow is 700grs. Finished arrow length is 31″ Ng to end of shaft (not insert).

One thing I forgot to ask is “are you content with your FOC or are you working to go higher”?
Troy

An old pilot’s saying: When in doubt, go higher. 😀

:D:D:D

Come on folks, don’t be bashful. Thirty viewers and only four posters (counting myself).
It’s just a bit of a servey to see what everyones thoughts are. If your not into high FOC let me know as well.

I’m very content, but the animals in my freezer are probably less than pleased about it. 😆

I pick my arrow up tomorrow Troy. Ill do the math and post. As for me and uping my FOC. I can say that Ill stop for now because the season is at hand.

Beman ICS Bowhunter 400, 50 grain brass insert, 100 grain steel adapter with a 130 grain Grizzly. 562 grain total with 25% FOC. Thanks and good luck! dwc

I’ll throw in something that will lift afew eyebrows. I’ve been playing around with a new setup. Just to twick things alittle I’m using a point alone that tips the scales at 454grs. Add in a 100gr brass insert and makes the point end weight heavy……
So far it’s shooting like a dream.
Want say anything else until all test are final.

Finally finished the new setup on the super high FOC shaft.
Final results are 37.2% UEFOC. Total weight of the arrow (fletched and shooting) is just over 800grs.
Totally amazing to see an arrow of that weight fly so flat and sink approx 3″-4″ deeper in my target.
Wish I had figured out how to make this setup before hunting season got here. Too late to change now.

Just wanted to be sure folks don’t miss that statement. I’ve been a bit reluctant to stress to folks the difference there is trajectory BETWEEN ARROWS OF EQUAL WEIGHT when one arrow is in the upper EFOC or UEFOC range and the other has Normal or High FOC. It almost has to be experienced to be believed, and is primarily a result of the rapid paradox recovery of the EFOC/UEFOC arrows, which conserves arrow energy.

225 gr tuffhead – 100gr brass insert
28.5″ shafts – 5″ fletch
Axis – 400 ——–730gr–efoc/29%
gold tip – 55/75 –722gr–efoc/28.5%
I have not shot any game yet with these, so will hold here until.
ScoutPS – I wanted to get above 650grs [ bone threshold ] to enhance my ability to cleanly take most game, out of several bows —

Troy,
I tuned my arrows to shoot straight and I got a pretty good FOC (25%), so how come that doe spooked out from under me yesterday??? dwc -

-
No, she busted me before I got a shot. 😀 But it’s great seeing deer in the woods. A pileated wood pecker, a red belly, a brown creeper and too many tree rats to count. Nice day in the woods.

My last attempt at reaching that hard to achieve 40% arrow yeilded 37.2%. I’ve ordered afew heavier fieldpoints (300gr screw-in) to try and increase my homemade adpt. weight. With the 225gr fieldpoints I got from Joe and alittle lead to fill the gap between the adpt and point I’m hoping to work up a point weight that will break 540gr.. Add that to the 100gr brass insert and 60gr. internial footing and I should have close to 700grs. up front. If this works and I doesn’t hit or pass the 40% I don’t think it can be done.

Don’t know mine, so apparently it is not critical. I shoot a wood arrow with a single blade/two edge head that flies well. Shoots through deer, so I guess that formula works. 😉 Wood shaft + sharp traditional head = dead deer.

Charlie,
I too have taken alot of game with woodies. Still, I’m always open for something better. From what Ed keeps telling me there is no such thing as overkill. What we are working for is an arrow that will break any bone in it’s way.
In the past I used 900gr hickory shafts and never worried about bone or penetration. When I started using carbon I tried everything from weight tubes to screen door splining to increase the weight.
Now that I understand the benefits of high FOC, I simply add the weight up front.
Troy

I suppose, and I do understand your goal, but to have a set-up that you are coinfident “will break any bone it it’s way” might encourage you to take iffy shots. I pass on bad angles because I don’t want any bone but a rib or two in the way.
The one I do worry about and it has caught me up twice is the spine from a treestand. I recently lucked by on margin because I had a 630 gr arrow with a small two-edged Stos 130 gr head that went through a vertebrae and on into a lung. I thought I had hit high in a rib but it actually made it into the spinal cord and on past. I couldn’t pull or push it out and snapped the head off with a pair of pliers so the butcher wouldn’t get himself on it. When I picked up my meat the butcher asked “what the heck are you shooting?”
Unfortunately, he dug out the piece of shaft still stick in it by sawing through the bone beside it instead of removing it intact. The bone with a section of Douglas fir shaft would have made a great conversation piece.

Charlie,
I’m sure you are right when you say some will use it as an excuse to take any shot.
As for me, your last posting is the exact reason I want arrows that will do the job better. Spines and elbows can for some unknown reason all of a sudden be right in the spot where your arrow is going. The shot may not have been intended for that spot, but at times you have no control of what the quick movement of a deer can put in your way.
Like Ed says, we aren’t trying to make an arrow for the perfect shot. We are making the arrow for that “oh c%@#” shot.

My current arrows are:
Easton Axis 400 spine 9.9gpi
29 9/16″ three 4″ fletches
Bear Razorhead 146 grains
484 grains total
16.1 % FOC
This is the arrow that I took my first Doe with.My new arrows are:
Beman ICS Hunter 400 spine 8.4gpi
28 15/16″ three 3″ fletches
Bear Razorhead 250 grains with adapter
528 grains total
24.5 % EFOCI can’t get over how well these new arrows fly. I’m considering hunting with them soon.

Jay,
Do you remember the fellow on TV that used to holler “MORE POWER”?
I’m the one that hollers “more weight up front” hehehehe!!!!
Troy
-
Troy, so I’m assuming that you think I should use the new arrows? They do fly really well, and I never did bareshaft tune my current arrows.
-
Jay,
If you didn’t bareshaft the lower FOC arrows and did bareshaft the higher, then yes I’d say switch to the higher FOC.
Doing so gives you two advantages over the lighter FOC arrows. Proper tune and more FOC.
