I already did a search and didn't find a direct answer to my question. So I need a little help/advice here.

When measuring FOC, Do you measure from tip of nock to tip of bh?

I am currently shooting a 380 gr. 27 3/4 Maxima 350 @ 70 lbs., at 301 fps. It flys great with a 100 gr. field point out to 80 yards. I think my FOC is under 9% currently.

I plan on elk hunting with this setup this fall and was looking to go to a 125 gr. bh, if it would give me better flight than the 100gr. Thus giving me a new total arrow weight of about 405gr, and hopefully a better FOC. I will need to purchase new 125 gr heads if I do this.

What do you think??

Two methods and both use the bottom of the groove of the nock. One method, that perferred, measures to the end of the arrow shaft - not the tip or insert (called Cut Shaft length). The other method includes the tip.

See FOC in General Archery Information. Diagrams and stuff.

I'm with dwagoner. The 125 gr bhead would be best weight for elk if the arrow flies good. Elk have thicker hide, bigger bones and a wide "boiler room."
