Extremely light broadheads

This may be obvious, but ...

If the FOC for a hunting arrow should be around 12 to 14 as I've seen on some posts, then how does anyone accomplish that with some of the ultra-light broadheads that Rocket sells? For instance, they have 57 grain heads. I haven't ran the numbers, but it seems to light!

You would, by your own F.O.C. constraint, have to be shooting a very light arrow. I played around with bowjackson.com's F.O.C. calculator and came up with a light arrow (?Carbon Express Linejammers?) of around 360grs. that had a 12.1 F.O.C.

If you shot a light poundage bow and short arrows, maybe the ultra small heads would be just the ticket to get a good F.O.C. A big 145gr head on a 27" arrow might not be the best...opinions?

The first thing to do is use feathers instead of vanes. Huge difference in weight and thus FOC. Some nocks are also lighter than others, thus affecting FOC.

I agree with the above statement. In fact this weekend, I wanted to do a test which was try different broadheads and measured the FOC anywhere from just under the 10% mark to over the 15%. I found that if you kept within the recommended range, the groups stayed more consistent. Or shall I say smaller. I agree that feathers will help with any broadhead but the trade off in my opinion would not be worth changing to feathers. They have their own problems.

Then there is always the fact that FOC doesn't matter.

Unless you are using a 40# recurve at 90 meters FOCget about it.
