EFOC without the IF?

[Kegan]

#7030

On NA game, the size of smaller hogs and deer, is an EFOC carbon arrow at the same risk of failure without an IF as when used on much larger game? I have arrows that are already finished out, they’re Beman ICS 300’s with a carbon collar, currently shooting 250 gr. Stos. I’m looking to get some 300gr El Grande Grizzly heads, but I’m worried. From what I understand the fracture occurs from a glancing hit on a dense bone, so I guess I’m asking if this set up would be a recipe for disaster if something goes wrong?

I’ve hunted with Beman ICSs (set up with normal FOC, for what it’s worth) for the past 11 seasons and have yet to ever have a shaft break going through an animal. As far as heavy bone on whitetail-sized game, Several years ago I put one through the upper leg bone on the off side of a whitetail buck (after going through both lungs). No damage; no problem.

Those shafts are tough; you should have absolutely no problems with durability.

You can also glue about a 1 inch piece of aluminum arrow shaft over the end of the arrow. I did that this year and have found that it protects the arrow from mushrooming or breaking quite well.

But as has been said, carbon arrows are plenty tough by themselves. No modification needed.

Thanks for the input guys. Steve, right now I’m using Carbon Collars, which accomplish the same thing (preventing mushrooming).

My set up right now is about 22% FOC or about, and so far my breakage issues while stumping have been few and far between (that includes on a couple glancing impacts that I swore were dead arrows). I just thought that I was really pushing my luck asking for more?

The aluminum external footings work extremely well. I have now eliminated using anything inside the shaft other than the insert. I have found that I can do all the strengthening and increasing front weight from the outside getting it closer to the tip. Closer to the tip, the more FOC you get.

Thanks for the input Sapcut! Have you had any issues with deflected shots breaking behind the footing?

No I haven’t but I also haven’t had enough shots in general to find out a lot of answers. I do know that I have made some hard hits and the arrow stood its ground.

For example…My arrow was about 820 grains. It had the double external footing like in the picture. It was traveling at 175ish fps out of my 71 lb. Widow recurve when I hit an iron man target made of 1/4 in. steel. The field point shaft broke off inside the brass insert and the insert collar was bent a small bit. The arrow was fine.

I feel sure without the external footing that I would have really shattered that arrow.

I really really like that type of setup.

I really like how your arrows are built, Richie. I think that may be the basic design that I will follow when I build my arrows for EFOC. What did you say your % was??

MontanaFord,
The arrow pictured above is as follows:
Shot from Black Widow PSAX 71@31

Gold Tip Ultralight Entrada 300
262 gr. 31″ from nock groove to cut carbon
210 gr. Grizzly El Grande
200 gr. adapter
100 gr. brass insert
30 gr. 2.5″ 2117 footing
27 gr. 2″ 2317 footing
9 gr. nock (after cutting 1/8″ off male portion)
6 gr. 3 – 4″ nanners
8 gr. glue

852 gr. 34.07% FOC

All my arrows are not identical but basically have the same blueprint.

Richie,

I’m shooting basically 60 lb at my draw length of 29 1/2″. Any suggestions what spine of arrow I might want to consider starting with? Perhaps something in the 75-80 or 85 lb range? What is your GT Entrada 300 spined for?

It is actually a .300 spine but I am not sure what the bow weight it is technically designed for. Although, I would guess it is a pretty large weight range.

I would think the GT Ultralight Entrada 400 would work for your 60 lb. bow. I use the 500 size for my sons 50 lb. bow. I load up the front on that as well, so the 500 starts off stiff for 50 lbs.

If interested I can let you know the best place I have found to get the Entradas.

Richie,

Go ahead and drop me an e-mail, so that I can save any information/e-mails back and forth for future use without having to search all of the threads on here. lol. How much FOC/EFOC did you get on your son’s arrows, and what did you end up with for total weight, etc? And the info where you get the Entradas would be great, too. Appreciate it a ton.
