Im shooting 410 up front. 190 grizzly, 125 steel adapter, 100 brass insert, 340 beman ICS hunter. Out of my 65# bob lee. They fly great and hit hard. total arrow weight is around 730 grains.

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.

C/E about 250 up front with wait tubes. 750total.  65# great northern C/G.  thud

You will tell once you encounter EDOA.  Extreme drop of arrow.      :rolleyes:

Yeah George or SIF. STUCK IN FOOT.  

350 up front of a 27" 35/55 gold tip.Shooting 48#@26".

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?

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.

The only EDOA i see is extreme death of animals.
