I'm trying to figure out how the FOC is figured and what % is recommended so I can do this for myself next time. Can anyone explain how to do this? I know the lumenok for the axis is 27.4 grains, the 3 blazers will combine for a total of 15, the 4 inch wrap will be 5 for a total of the rear of 47.4 grains. The front will have the 100 grain head and I believe 16 grains for the insert. This is as far as I know how to take it. Thanks for the help.
measure from the nock where the string bottoms out and to insert at the other end. divide that number in half. then with the broadhead on the arrow just simply balance arrow on your finger and mark the balance point with a pencil. then measure from the insert to the balance point. take that measurement and subtract it from the number you originally divided in half. then take the number get from the subtraction and divide it by the over all number you first measure and that will give you the foc. some say 12 to 15 percent is good. some say 10 to 12 percent. i'm shooting 11.25 percent and have no problems
