I have read a few things about FOC and understand it and the whole concept is basic common sense. But what i am confused about is that i have seen that majority of people it seems that its best to have and FOC of 10-12%. My question is why stop there? Why not get as much FOC as you can? Whats the affects of haveing an FOC really high?

The speed freaks are gonna say loss of speed anda less flat tajectory leading to bigger pin gaps.

My arrows have a 24% FOC and hit like a Mack truck.

Right! I'm shooting 21%, and wouldn't think of shooting less, EVER!

It really causes your arrow to drop? i would think it would be more stable during flight that it would have a more flat trajectory. How much of a speed loss we talking? A few feet per second or is it a trastic change in speed?

High foc equals forgiveness , good arrow flight especially with broadheads , and if you are a hunter , better penetration

Im running around 14 to 15 now and would love more

I think he meant drops more because of overall arrow weight. If given 2 arrows both weighing 500 gr total, one with 12% FOC, the other 24%, I doubt there will be a noticeable difference in trajectory. After shooting traditional gear with a high FOC, next years setup for my compound will have a high FOC too.

well i ment a heavier tip. take the same arrow with a 85 grain tip vs one with a 125 grain tip. That will change the FOC but will it drop enough to notice? Im not really seeing how it would. Yea now the arrow weighs a little more but at the same time you just moved the FOC forward more so its a little more easier for the fletching to stablize the arrow. I guess the best thing for me to do is just mess around with some different arrow setups and see what happens.

I shoot 20% and really like this combo. On some compounds, I only shoot 11%. I have to admit, it does nose dive the arrow past 50 yards. But I don't shoot much past 50 yards.
