front on center
 

whats % do you want to be front on center for bolts ,are they the same as long arrows?
I did my calculation and mine came up with 9.28%
Im using gold tip game crushers 22''
its 14.2 grains per inch and im using 100 rage.
I would like to put on luminoks,so going to change the percent.
To off set it, i was thinking of brass insert or brass washers.
I dont think putting more than 2 washers is a good thing.
The bolt weight is 370 grain thats without the tip.
What happens to the bolt when you have to much or not enough % front on center?
Thanks

Arrows
 

Anthony,

Thier arrows not bolts. Your FOC (Forward of Center) is a bit low. You probably would be better off going to a 125gr Broadhead.

what would be a good % i should be in.I would like to add luminoks on that arrow,should i go for a brass insert pluss 125 grain broadhead?
thanks

Set your bolts (and, yes, the short "arrows" used for crossbows are called bolts) up the way you want them and don't worry, too much, about FOC %. If you are getting good flight, just shoot them.

If you aren't getting the results you expect, or if you just want to experiment, it's simple to add weight to the nock or point end and check the results.

The ideal FOC % is purely subjective, depending on your equipment and what you are aiming for. Some short yardage and 3-d shooters try for 7-9% while some longer range shooters try for 12+%. The fact is, the majority of bowhunters out there will give you that "deer in the headlights" look if you ask them what their FOC % is.
