Choosing a Compound Bow
by Brian Wensel 
Rule number one; do not
“out bow” yourself. You do not need to
shoot a 70 or 80-pound bow to successfully take a whitetail. I have hunting bows that range from 50 to
70-pounds and setups that are geared toward specific hunting situations. For the majority of deer hunters, a 60-pound
compound bow at ranges out to about 30 or 35 yards is more than adequate. If you are planning to hunt in the Midwest
for elk and expect to take longer range shots of 40, 50, or even 60-yards then
you might want to consider a 70 pound bow with a higher kinetic energy
rating.
What is kinetic energy? Basically, the more your
arrow weighs and the faster it flies, the more kinetic energy it will produce
at impact. Think of kinetic energy as
the amount of punch your arrow has when it hits the target down range. Kinetic energy translates directly into
penetration and pass through. On medium
sized game (deer) the recommended amount of kinetic energy is 25 to 42 foot
pounds and 42 to 65 foot pounds for larger game such as Elk. Many of today’s bows have a kinetic energy
rating that exceeds 80 or 85 foot-pounds!
That figure is normally calculated using a 70-pound bow and a 350-grain
arrow. So as you can see, you don’t have much to worry about, unless you are
planning to shoot a 30-pound bow, then you might have issues, especially at
longer ranges. The farther your arrow
flies, the less kinetic energy it will have when it impacts your target. If you want to read more about kinetic energy, check out Dewclaw Archery's
Kinetic Energy Calculator Let Off. Think of let off as the amount of energy the
bow is holding at full draw. Most bows
today have a let off range of 65-80%.
With today’s fast and efficient bows, let off isn’t that much of a
factor in my opinion. It simply makes
for a relaxed experience when at full draw and allows you to comfortably hold
your sights on the target longer before your arms start to shake. Think of it like this. If you had bow with a 100-pound draw weight
and 85% let off, when at full draw you are essentially only holding back 15
pounds.
Brace HeightBrace height is a measurement that
is taken from the inside of the grip to the string and can be found listed in
the bow’s specifications. Brace height can also directly impact how well a bow
shoots. The higher the brace height, the
more forgiving (easy to shoot) the bow is when shot, which contributes greatly
to consistency. Anything over a 7-inch
brace height, which is quite common, will make an excellent hunting bow. There are bows on the market with brace
heights as low as 5 inches that claim to be lighting fast. Well, you have to ask yourself, do I want to
sacrifice forgiveness, and possibly consistency, for an extra 20 feet per
second? With most bows shooting over 300
feet per second these days, I’ll take the forgiveness. But that is for you to decide.
Bow SizeThe size of a bow is also
important when spending long days hiking the hills, crawling through the brush,
or even sitting on stand from sunrise to sunset. A long, heavy bow can quickly become a burden
and that extra few ounces can really make your shoulders burn at times. A 38 inch bow with a 5 inch brace height
might work well at an indoor tournament in a controlled environment, but don’t
put that bow in my hands in the whitetail woods. Every bow has a purpose and an environment in
which it performs best. There are target
bows and there are hunting bows…choose wisely.
Draw LengthOne common mistake is to visit
your local sporting goods department, grab a bow off the shelf and take it
home. You will never accurately shoot
that bow unless it has been fitted for you.
By that, I mean your draw length.
A bow that is too big (draw length too long) can cause you too feel
stretched out at full draw and will often cause the string to smack the inside
of your forward forearm, leaving a ridiculously painful welt on your arm. Trust me, if you’ve ever done it you know
exactly what I’m talking about. If a bow
is setup with the proper draw length, the knock of the arrow should be located
approximately at the corner of your mouth when at full draw. This allows you to lean your head slightly
forward in a comfortable position when aiming.
My personal preference is to have my draw length set ½ inch less than my
measured draw. Make sure you have your
draw length properly measured by a professional like those at the Dewclaw
Archery Pro-Shop. You can also use Dewclaw's

Draw Length CalculatorBasic RecommendationsIf I were to recommend a bow for a beginner
hunter I would stick to the following parameters and you will have a solid,
good shooting bow that produces consistent results, even when taking contorted
shots hanging off the side of a tree stand. Size: Axle to Axle length of 34 inches or less,
maneuverable and lightweight.Draw Length: Ensure you are properly fitted by a
professional.Let off: 65 to 80%Brace Height: 7 inches or more.Draw Weight: Depends on your abilities. 60 pounds works well for deer, but so does
50, or even 40 if your setup is properly created. You should be able to hold your bow in front
of you and easily draw without any ridiculous contortions and twisting while
drawing. If you do, the draw weight is
too much, back off.
You will find when searching the
web for bow specs that most major compound bow manufacturers have a wide
variety of bows that fit into the above recommendation. Narrow your search to a few models, find a
local dealer and go in and shoot them all.
Find the one that “feels” right in your hands, because ultimately that
is what is most important. Confidence in
your gear, gear that feels like an extension of your arm when shot, makes for
an enjoyable archery experience.
