FOC?

[et1702]

No, more FOC is better.  I shoot a 150gr BH.  My FOC is almost 19%  Go to AK Bowhunting web site and look at explanation of FOC.  Lots of other great info too.

Sorry about the delay, my current set up is at 8.14% for the FOC. Should i worry about it being too low?

Only if you have noticable flight problems......I would look at weight on the back end, its one of many reasons I use AAE fletch...its very light.  If it was me. I'd look to get rid of 5 to 10 grains off the back end rather than add 25 up front.

Way low IMO!  I know that some say 7 or greater is okay.  However start reading up on it and there is definitely advantage to hedging you bet and upping FOC.  I say at least 15%,  on my compound I am at about 21% and long bow is 29% (memory is fading it has been so long since I have changed anything.  Trick is to try different arrows and lengths, broad head weights, and ect. to get the flight you want.

If you want to disregard FOC all together, get some Arrow Dynamics....Orange Stingers for me....tapered shaft means no FOC problems, natural weight forward design.....I shoot 85 or 100gr broadheads depending on which and what.......

Last I e-mailed them, they will sell direct to user.

Hey Dreamunelk, regarding the FOC of your longbow arrows: If your arrow length were 29" (from the throat of the nock to the back of the point), your balance point would be just shy of 23" from the throat of the nock! Do you have a Buick on the front end of your arrow?  Talk about a new slant on the term "Drive-thru."

200gr BH give a little forward lean.   I has been awhile since I checked.  I am pretty sure that was it I know that i was close to the 30 mark.  A few out there would say go higher.   Once I find something that works I tend to stick with it.  Also using spruce for my arrows.

I've 23/64" spruce shafts that I tapered full-length, 4-1/2" feathers, plastic nock and a 190 grain broadhead; that extra ten grains you have must really make a difference. Or are your shafts also footed?

[dreamunelk]

So long as the arrow flies right I don't know that there is such a thing as too much FOC.

Doesnt more FOC mean more penetration?

Yes, that is what studies have shown.
