Semi-Auto vs. Bolt Action

There is an ongoing topic as to whether someone should purchase a semi-automatic precision rifle, or a bolt action, and why. There are a few key variances in both which make them very different. One may present itself harder to shoot or less accurate, while the other may be held on a pedestal.

Typically the bolt action precision rifle presents itself as being the most accurate in comparison to a semi-automatic. However, this depends on numerous other factors with regard to both firearm and ammunition, and modern semi-automatic rifles can be exceptionally accurate when designed as such. Some of the factors that precision shooters take into consideration when accuracy is discussed between the two platforms are:

- Recoil

- Gas release

- Moving components

Recoil The bolt action rifle when fired, has only one recoil, this being recoil to the rear into the shooters shoulder pocket. The semi-auto precision rifle when fired, has three recoils, one recoil being to the rear as the bullet exits the muzzle, another recoil to the rear as the bolt slams into the buffer, and the final recoil as the bolt slams forward picking up an additional cartridge.

The bolt rifle only having a single recoil to the rear, in some cases allows the shooter to “drive the rifle” in a superior manner.

Gas Release When a cartridge is fired inside the chamber of a bolt action rifle, the force from the burning charge and expanding gases is directed at propelling the bullet down the barrel, however, some of the energy is transferred to the shooter through its normal recoil. Unlike the semi-automatic rifle, some of the energy used to propel the bullet down the barrel is used to cycle the action.

Moving Components

The moving components within the two rifle platforms may also present one to be superior to another. Typically precision rifle shooters prefer the bolt rifle simply due to its lack of moving components. Taking a look at the bolt rifle, the only moving part is the bolt, which is manually operated by the shooter. Once the bolt is locked, the entire rifle is merely one solid component, thus making it easier to control through recoil, and avoiding bullet impact deviation downrange due to shooter induced movement of a moving part on the rifle.

The semi-automatic precision rifle will always have a moving part at some section on the rifle, usually this being the upper and lower receiver. If you’ve ever looked through the scope while in the prone position, the slightest movement with your firing or support hand, you can notice that the upper receiver will slightly shift left or right, or in some cases, up or down. This slight shift/movement within the scope may be caused by a number of reasons, shooter flinch, undue sympathetic squeeze as rifle is firing, etc. As the shooter begins to fire or begins to perceive recoil, the shooter may cause the upper and lower receiver to shift where the two components meet, thus causing a change in desired point of impact when the rifle is fired.
