Howler,

That sounds way off buddy. Double check it at bowjackson.com.

Yip, I did it wrong, it turns out that I only have a FOC of 7.8%! So, to increase that, I need to do one of several things? I could shorten my arrow and keep using 100 gr. tips, or go to a heavier tip? Or do both? Is that right?

Howler,

Try going to 4, or 5 inch feathers. That will help your FOC, and as long as it doesn't lighten up your arrows too much for your liking, than you should be fine.

This is where a GOOD pro shop comes in handy. Stop in and see them, and have them help you compute all of your options until you come up with a perfectly matched arrow!

howler what is the distance between the balance point and the center mark?

Bigpapascout

Howler if I calculated right the distance is 2.75" which gives you a forward of center of 9.64 whick IMO is perfect.

Howler

Well, I happen to have some 125gr. judo points here that I just screwed in, and they moved the distance from center of arrow to balance point from 2.25" out to 3.25", which gives me a 11.4% FOC. So, looks to me like I need to get some 125 gr. field points and see if that helps my arrow flight. Although, I just put on my drop zone, and sure seems that I was already getting pretty arrow flight, with field tips. But I assume, my fixed blade heads won't fly nearly as well with the lower FOC, so I'd be better of going to 125 gr. broadheads?
Is that right?

Foc is overrated , strait arrows spine matched with the correct amont of fletching , and broadheads that are on strait , will give you good results . All those things will keep you busy . Oh and I allmost forgot good nocks that fit right . All the arrow setups I have checked have been between 9 and 13% .

howler
use what you want to use
but I would stickwith the 100 grainers

Howler

I think I will do that papascout. I am going to try to shorten a couple of arrows, one by an inch and another by two inches, and do some self testing from there. Apppreciate the help!
