For most whitetail hunters a two inch, two blade rear deployment head with a chisel point is the ticket to a quick kill and a good blood trail. If you look at what and why we use a broad head instead of a field point, I think this question is answered for most of us. We need broad heads to cause the wound to hemorrhage causing either a heart attack or suffocation, which is quicker than a small single hole like a field point. Secondly, we need a tip that shatters a bone when it's hit, which in turn does not use up our available kinetic energy or momentum and the best for this is the chisel point. If you process your own deer you will be keenly aware that the bone of a deer and the bones of livestock are not the same. A deer’s bone is much harder and more brittle than livestock. Try sawing a deer’s leg off with a bone saw meant for cattle, you will get a big surprise. So what kind of broad head do I recommend? Glad you asked. Across the whole weight range of bows and set-ups, a design like RAGE® Hypodermic 2 blade 2” broad head or in the 50lbs range or less 1-1/2” of the same variety. REMEMBER - Conserve your kinetic energy and get a pass through and a good blood trail. Good hunting to all in the upcoming Bow Season!!!!
Putting an arrow in a bow, that is heavy with more spine, does not mean you will see a difference in performance of the penetration. This is because the way to change kinetic energy in an arrow by any appreciable amount is by changing the bow; yes that’s right I said the bow. Sometime when you’re not doing anything, play around with a Kinetic Energy calculator. I believe that you will be surprised. The best way to get more penetration is to “Bow up” or change the style of broadhead you are using, unless you’re shooting an 80 lb bow with a very fast IBO speed rating. You will be disappointed with a three blade mechanical broadhead unless it is a rear deployment style. Considering which arrow construction to use has more to do with the cam design, draw weight, arrow rest, and release that you will use. Below is an actual test of my bows and arrows that I personally use.
Calculate percentage difference in Kinetic Energy
between Ke1 = 77.56Ke and Ke2 = 79.9 Ke
[(Ke1 - Ke2) ÷ ((Ke1 + Ke2) ÷ 2)] * 100
= [(77.56Ke - 79.9Ke) ÷ ((77.56Ke + 79.9Ke) ÷ 2)] * 100
= [-2.34 ÷ (157.46÷2)] * 100
= (2.34 ÷ 78.73) * 100
= 0.029722 * 100
= 2.9722% difference in Kinetic Energy (that’s right, gaining less than 3% Kinetic energy)
Calculate percentage difference in Speed
between V1 = 326 and V2 = 302 (measured in feet per second “fps”)
[(V1 - V2) ÷ ((V1 + V2) ÷ 2)] * 100
= [(326fps – 302fps) ÷ ((326fps + 302fps) ÷ 2)] * 100
= [24 ÷ (628 ÷ 2)] * 100
= (24 ÷ 314) * 100
= 0.076433 * 100
= 7.6433% difference in Velocity (that’s right, more than 7.5% loss in speed)
I am a hard case fan. They are the most versatile. You can use them on a four wheeler, in the bed of a pick-up truck, at the airlines, and in the trunk of a car. The hard case provides total protection of a very expensive piece of equipment that has become an investment. And let's face it, bows are NOT getting any cheaper!
