Broadhead grain weight are a measurement of how much a broadhead weigh. The grain weight of a broadhead determine how the arrow will perform when the person who owns the arrow fire it. The grain weight of a broadhead affect the arrows momentum and its ability to penetrate the animals that it is hunting.
The relationship between the grain weight of the broadhead and the design of the broadhead are important to understand. Fixed-blade broadheads is known to be more reliable as they dont have any moving part like mechanical broadheads. However, mechanical broadheads has blades that deploy upon impact with the animal.
Choosing the Right Broadhead Weight and Type
As such, more kinetic energy are required to deploy the blades of a mechanical broadhead as opposed to the blades of a fixed-blade broadhead. Hybrid broadheads has the benefits of both types of broadheads as they have one set of blades that is fixed and the other that deploy upon impact. However, due to the protrusions of the blades on mechanical broadheads, they are more susceptible to wind drift then fixed-blade broadheads.
The diameter of the cut of a broadhead is related to the grain weight of the broadhead and the type of animal that is being hunted. Narrow cut are used for broadheads that require more momentum to penetrate the thicker skin of animals like bears. Wider cut are used for animals like deer whose thick fur requires more blood loss when hunting them.
Using a light broadhead with a wide mechanical design will not allow for good penetration into the thick bods of large animals. Using a heavy broadhead will change the front of center balance of the arrow. The front-of-center balance of the arrow will allow the arrow to travel further with increased penetration power.
The draw weight of the bow will determine the weight of the broadhead that will best suit the arrow. A compound bow with a 50 pound draw weight can utilize 100 grain broadheads, which are the weight of broadheads that is often used to hunt deer. A compound bow with a 70 pound draw weight has the energy necessary to use 150 grain broadheads to hunt large animals like elk or boar.
Additionally, the spine of the arrow is also important to ensure that the arrow does not develop any inaccuracy in the flight of the arrow. Depending on the type of animal that will be hunted with the arrow, different grain weight of the broadhead and different designs of the broadhead will be required. For animals like turkey and small game, light mechanical broadheads is used.
For deer, either fixed or mechanical broadheads of the midweight can be used. For animals as large as elk and black bears, the heavy broadheads with at least 150 grains of weight should be used. For wild boar, whose shoulders is thick with bone, narrow and heavy fixed-blade broadheads are used to ensure good penetration of the broadhead into the bone structure of a boar.
The number of blades on a broadhead can also impact the function of the arrow. Two-blade broadheads are made to drill deep into the animal. Three-blade broadheads is the most common as they balance the need for a wide cut with deep penetration.
Four-blade broadheads will create a wider cut on the animal but reduce the velocity of the arrow. The material from which a broadhead is made will also impact its grain weight. For example, stainless steel is a durable material for making broadheads.
Aluminum makes for light broadheads. Finally, titanium is a strong material for making the broadhead but cost more money for its use. In order to properly set up the arrow for the hunt, there is steps that should be followed.
First, ensure that you have shot field points at your target to ensure that your arrow is accurate. Second, ensure that you are shooting the specific grain weight of the broadhead that you intend to use when you go into the field. Third, ensure that your blades on the broadhead are sharp as sharpness will impact the penetration of the arrow into the target animal.
Finally, ensure that you take into account the angle of the shot that you will take at your game animal as light broadheads are best used for broadside shots while heavy broadheads are used for quartering shots.
