How Much Draw Weight For Hunting?

Before we dive right into how much draw weight you need for hunting let’s take a look at what draw weight is and how various factors go into determining what the proper draw weight is for you.

Bowhunter at full draw

Bowhunters want to shoot as much draw weight as they can comfortably hold back for long periods of time should the need arise.

What Is Draw Weight?

Draw weight is a measurement (in pounds) of the force required to draw (or pull back the string of) a bow.  Theoretically, “drawing” a bow that measures 70lbs requires the same amount of force as it would to lift a 70lb weight from the ground, obviously the movements would be different but the resistance would be the same.  The draw weight is influenced by a few factors, but the most notable is the stiffness or rigidity of the limbs. So, for instance, a bow with a maximum of a 70lb draw weight will have stiffer limbs than a bow with a 60lb maximum draw weight.

The amount of this resistance (or draw weight) is adjustable by about 10 pounds on most compound bows.  In recent years bows for kids and women have been designed to allow significantly more adjustment in draw weight, sometimes as much as 50lbs.  This allows for kids to increase their draw length as they grow and get stronger, without having to replace the bow or limbs.  The marked draw weight on a bow is the maximum amount that the bow is capable of reaching, so a 70lb bow will typically be adjustable from 60-70lbs, a 60lb bow will be adjustable from 50-60lbs.

For traditional bows such as recurve or long bows, the draw weight is designed to be a specific amount (say 55lbs) at a particular draw length (say 28”).  If the string is pulled back further than the set draw length the draw weight will be more, the opposite is also true.

What Is Let-Off?

The term, “let-off” is used to describe the amount of draw weight required to hold the bow at full-draw.  Let-off is measured in a percentage of the bow’s draw weight.  For example many compound bows have 75% let-off, what this means is that when the bow is fully drawn, the shooter is actually holding back 75% of the draw weight.  So a compound bow set at 60lbs with a 75% let-off means that the shooter has to hold 15lbs to keep the bow at full draw.

Recurve and long bows do not have let-off.

Why Is Draw Weight Important?

Draw weight is important because it influences the speed at which the bow can shoot an arrow, also, it is imperative that the draw weight be comfortable for the shooter in order to have proper form and to be accurate.  Many people try to shoot too much draw weight so that their bow will shoot faster, but this keeps them from having proper shooting form and also hurts their ability to shoot accurately.  This can be especially important for bow hunters who often sit for long periods of time in inclement weather or hold their bow back for long periods of time.

What Draw Weight Do I Need?

A comfortable draw weight is different for each shooter.  Some shooters are capable of shooting 70, 80 or 90lbs, but most adult males shoot between 60 and 70lbs.  Today’s bows are extremely efficient and 40lb compound bows are more than capable of harvesting many big game animals.  For whitetail deer hunting anything above 40 lbs is fine.  For larger game such as elk or moose a good recommendation is at least 60-65 lbs of draw weight.

A general rule of thumb is that a shooter should be able to shoot a bow about 30 times in a row without being fatigued. If the shooter cannot draw the bow 30 times the draw weight should be decreased.

What Is The Minimum Draw Weight For Hunting?

The minimum draw weight that is legal for hunting may differ for each state, it is important to check the state regulations in which you plan on hunting.  In most states, the minimum required draw weight is 40lbs.

How Do You Adjust Draw Weight?

Adjusting draw weight

When adjusting draw weight it’s imperative that you adjust both top and bottom limb bolts evenly.

Draw weight is usually adjusted by tightening or loosening the limb bolts on the bow.  The limb bolts will most likely use an allen key to adjust them. The amount of change is different for all bows but generally speaking, a full turn (one direction or the other) will change the draw weight by 2-4lbs.  When adjusting the draw weight, it is important to adjust the limb bolts on the top and bottom limbs equally.

    One major problem which happened to me was damaging the body.
    I was shooting every day consistently a comfortable weight for me (the more the better).
    I eventually damaged my shoulder. As long as it can be done, the body will say OK, however, there will come a time for some avid archers when the body will give in and then you could be out for a while and possibly retain a permanent side effect with your ability to shoot.
    My rule of thumb is when I am comfortable with the weight, back off five or so.

  2. I’m not sure I understand “let-off.” you say “let-off” is the percentage of the draw weight you are holding back to keep it drawn. if many bows are 75% let off, that would mean you are holding back 75% of that, lets say, 60lbs. 15lbs is not 75% of 60lbs… that would be 45lbs. am I wrong?

    • Letoff is the percentage of weight that drops, or “let’s off” when you come to full draw. So if you have a 75% let-off bow with a 60 pound draw weight, it let’s off 45 pounds and has a holding weight of 15 pounds. The greater the let-off percentage the less holding weight at full draw.

      You ate right, 75% of 60# *is* 45#. This is the amount that the draw weight will be *released* and the archer will need to deal with what’s left over. So our hunter starts with a 60# draw and at a certain point the bow will release 45#. From that point back to full draw our hunter is pulling and holding only the remaining 15#.
