Are heavier points more accurate?

<< < (3/3)

billy:
Dr Ed Ashby did some penetration test and he said that arrows with an extreme FOC (forward of center) balance point will increase penetration.  But he was testing his arrows on big, heavy-boned animals like water and cape buffalo.  I would think that a reasonable compromise with our bows and arrows would be perfectly adequate on deer-sized game.  From my experience, perfect arrow flight is the number one goal I shoot for.

...pun intended, right?  ;)

Rhinegold:
Can anyone think of a disadvantage to extreme FOC?

What would be the downside to a FOC of say, 50%?

Kegan:
I'm not sure what you'd have to do to get to THAT point,  but higher FOC's, as Billy said, can help.

It works like a dart. A heavier point makes it easier to throw. Likewise, in flight the heavier point resists the archer's paradox more than a lighter point. So the arrow striaghtens out a little faster- if it's matched to your bow, this means more retained energy and a straighter flying arrow. They require less fletching as well, which means a faster arrow (provided the higher FOC didn't cause the arrow to become too heavy).

I've seen some shorter arrows with as much as 30% FOC, but I think trying for 50% would be pushing the reasonable window. But who knows? Maybe if you get it going it will be a great arrow.
