Here’s a real hunting example of FOC’s effect on arrow penetration, and is for one of the many arrow setups used in the testing. At 31.4% the 655 grain, eleven-factor arrow (it had a light-weight parallel shaft) achieved a near-passthrough on a hunted mature Asian Buffalo bull, hanging up on the buffalo’s off-side shoulder by the tiny A&A fletching.

This shot was from approximately 20 yards on a trotting buffalo and was from my 82# longbow – at what most would consider ‘very low velocity’ and which the ‘recommended guidelines’ consider to be ‘inadequate Kinetic Energy’. That’s why FOC is such an important factor.

The important takeaway is: the higher you can get your arrow’s FOC, while maintaining structural integrity and perfect arrow flight, the greater your arrow’s penetration will be.

The potential increase in arrow penetration at the upper limits of arrow FOC is enormous.

Q. Do tapered shafts really make a difference?

A. In short - yes. With normal to high FOC ar
