Scroll to bottom of page and use the arrow building simulator

 

Not to high-jack thread, but I've been wondering about this, too. I used the simulator you posted link for... 448 gr arrow at 9.7 foc. Any suggestions for how to get this higher? I shoot Beaman ICS 340 shaft, blazers, 100 gr BH. I like my heads, just want to add some weight up front. Thanks for any suggestions

 

little washers, that add as spacers can be used to bring the weight up by a bit and improve performance greatly

 

I use brass inserts from 3 rivers archery they come in 50grn and 100grn

Just be careful adding too much weight to the front can mess with spine.

 

You can find an FOC calculator but I can't tell the FOC with out knowing the balance point of the arrow

 

Oh my FOC calculator you need to input the shafts balance point

That sheet states field points should be a lesser foc...I disagree. My setups with broadheads and fieldpoints should be exactly the same FOC or as close as possible. Otherwise you're not doing your hunting set up justice.

 

444 grain arrow, 13.4 % FOC. Sound about right?

Never thought of that. If they are the same grain weight wouldn't the FOC be the same? If so it won't effect me
