Adding to FOC

[oldfarmsblueman]

I checked my hunting arrows for FOC Not sure but think
I need more up front?
PSE Radial x weave 100'S 100 gr BH= FOC 10.0
85 gr BH = 8.6
75 gr BH =7.7
Beman 500 100 gr BH = 10.4
85 gr BH = 9.4
75 gr BH =8.4
If FOC for carbon arrows is to be 12-15 how do I add the extra
up front. or do I???

I have shot 8% for nearly 20 years and dont go above or below it.
I have gone 12-14% back 30 years ago and stopped when I realized the effect of FOC on flat flight.
Same arrow weight corrected to 8% wll gain a yard or two in some instances...depending on the set up.

I agree with BT - mostly - However, I find that if you hunt in high wind, a bit more FOC does good things for you with regard to arrow stabilization. Due to the fact that any extra weight on the arrow will cost you on flat flight - it is a pain to have light arrows for calm days and heavy arrows for windy days. So - I have since gone the other route: I like something closer to 12% for hunting arrows. To get the FOC with carbon arrows, I still shoot 100 grain tips for the lower profile, I add screw in weights to the back of the insert. Use epoxy to hold these guys in place, and make certain your hunting and target tips screw in all the way before allowing the glue to set! This give me the extra FOC, and I get to use a smaller profile fixed blade hunting tip. I still get a tad over 300 fps, even with the extra weight, so I don't care a whole lot about a small loss of flatness of shot.
