Air Rifle Actions and Type of Power Source

Hunting is entertaining in the US. Each year, when autumn begins and last until winter, the hunting season starts. Hunting with air rifles is challenging, and demanding, and using air rifle will demand you more than in any other types of sporting. As an air rifle hunter, you must present the ability to have an accurate and cleaned kill shot, as it will show your field craftsmanship utmost with respect for your quarry. For many sportsmen, rifle hunting is also behavioural sportsmanship, a connection with the nature around and its beauty. Yet, there are number of factors required to make a clean, effective shot at a turkey, or a deer rather than only pulling the trigger with a hope in your mind.

Airguns have not had much wide use within the main hunting community in the US, unlike Europe or the UK. In recent years and over the last decade, the present of airguns are more visible as you might see that there are more states are setting up their airguns hunting regulations every year. Most states allow airguns to be used for small game, varmint, and predators. At the present, some states allow airguns to be used for whitetail as well. They are many hunting jurisdictions opening their hunting seasons not only for smaller game. So, the state wildlife management agency comes to the scene.

In many parts of the world, air rifles cycled spring-powered are widely used for smaller game. More recently, there is an increase in the number of hunters using pre-charged pneumatic rifles for small game, predators, and even in larger game.

Air Rifle ActionsRifles are classified based on their actions. There are single shot action and repeating action. All rifle actions operate in the same five steps: loading feeding, firing, extracting, ejecting.

There are five types of rifle actions in used today:

  • Bolt-action
  • Pump-action
  • Lever-action
  • Semi-automatic action
  • Break-action

A bit about air rifle history, these rifles have all been around for a long time. The bolt, pump, and lever action rifles have been there from the 19th century, while the gas powered operated semi-auto rifle was discovered and developed in the 1930s, and was well introduced in the end of the World War II.

To give you a basic idea of how they work, the single shot rifles are usually operated in break or bolt action. Repeating actions include the bolt-action rifles, pump-action rifles, lever-action rifles, and semi-automatic types of rifles. The empty cartridge case is ejected after a fire, is shot when the shooter operating the gun’s lever, bolt, or forearm, and chambers a new round of ammunition; the gun is cock and ready for a new shot. With the exception of the auto action, other actions are more effective in operation when they are cycled with force. So, just slam those bolt handles and levers no need to worry it will harm your rifles!

Power Source using for Air Rifles

Air rifle ammo types and power source are generally divided into 3 groups: Spring piston, Pneumatic (Pump), and CO2-powered (compressed gas). In Spring piston there is gas spring or Nitrogen piston rifles, and in Pneumatics there are single stroke, multi-stroke, and Pre-charged Pneumatic rifles.

Air rifles and handguns are designed based on each group of power source to have a suitable action and operate in the respective mechanism. The below terms and classification will help you understand clearly what is rifle caliber, what is a bullet, and what is a cartridge so as not to mistakenly using it when you are into hunting and as a beginner hunter.

Caliber: Rifle and handgun are measured by caliber. Caliber is the diameter of the bullet or the gun’s bore. It is measured in both metric system and in hundredths or thousandths of an inch. The measurements in metric are always a “diameter to length” ratio. For example, a bullet in caliber 5.55x40mm means 5.55mm wide and 40mm length.

Bullet: is the projectile in a cartridge that will exit the barrel when the gun is cock and fire. People often use the word “bullet” when their actually need is a cartridge. Therefore, bullet should not be used interchangeably with the word “cartridge” because it is only a component of a cartridge. Some gun beginners would normally confuse between these two terms when they go to a gun store. In rifles and handguns, the bullet is contained inside the cartridge case.

Cartridge: A cartridge consists of 4 components, they are:  Case or cartridge shell (usually made by nickel, or steel), primer, propellant (or gun powder), and the projectile (or known as the bullet as mentioned above). The measurement of a cartridge is the number of powder grains it is designed to hold. For example, if you want to get a .30-’06 cartridge, the first number is the caliber size, and the second number means the cartridge case can hold six grains of gun powder. Some people would often tell the gun smith to get him/her a .30-’06 bullet, but what he/she needs is a cartridge.

The cartridge type is important because choosing the right cartridge and suitable to the hunting game you need will guarantee a clean kill and preserving as much of the meat as possible. For example, if you use more powerful ammo than what you really need for your hunting game, then the animal is hunted down quickly without suffering but there may not much meat remain after you shoot them. Alternatively, if you use weaker ammo in a larger game, the animal could not be killed right on the spot and it could suffer in pain a long time before dying.
