Remember as a kid when
Remember as a kid when you shot an arrow high into the air and were delighted when it stuck in the ground, point first? It stuck because its metal tip made the arrow front-heavy.
While aerodynamics are more complicated than that, what you should know is that by manipulating your arrow’s FOC (Front of Center) weight, you can alter its ballistic characteristics to your advantage--and the best way to do this is to go with a heavier broadhead.
When a bowstring is released and an arrow takes flight, energy rapidly transfers down the shaft to the tip. Once this happens, the arrow is essentially pulled through the air by the tip, rather than pushed by the nock. This allows smooth steering of the arrow, and also increases momentum and therefore penetration when it strikes a target.
Most experts agree that fixed-blade broadheads fly better with an FOC of 12 to 18 percent, with 15 ideal for most hunting setups.
So why don’t all arrows have greater FOC built in? The main reason is that a 15-percent FOC doesn’t come without some tradeoffs. First, if weight is simply added to the tip, it results in a heavier overall arrow and therefore is slower by a few FPS. Slower arrows don’t shoot as flat, and they don’t sell as well. Secondly, arrows owning a higher FOC drop at an exponentially faster rate as range increases.
However, JJ believes those negatives are worth the higher FOC’s advantages. For one, laser rangefinders have made higher arrow speeds/flat trajectories nearly a non-issue for hunters. Secondly, accuracy generally increases. Third, gains in penetration is dramatic. Four, shooting heavier arrows reduces bow noise, and finally, a heavier broadhead can be built more robustly so that it can survive violent impacts with bone and still penetrate through game for quick, ethical kills.
In this video, JJ teams up with noted FOC advocate and Youtube personality Troy Fowler, AKA The Ranch Fairy, along with a former missile/rocket engineer from the US Military to capture data via a Lab Radar/Dopper to actually learn what the arrow in doing downrange in terms of velocity, energy and momentum.
This fall, if you aren't shooting 125, 150 or even 200 grain broadheads, you should be. There's really no downside.
