The .22 Short and the .22 Long Rifle (often shortened to .22LR) are two of the most popular rimfire cartridges globally, favored for target shooting, small game hunting, and plinking. While both share a similar diameter, their performance, and consequently, their noise levels, differ significantly. This article delves into a detailed comparison of the noise produced by these two cartridges.
Understanding the Differences: More Than Just Length
The primary difference between the .22 Short and the .22 Long Rifle lies in their cartridge length and powder charge. The .22 LR is considerably longer, allowing for a substantially larger powder charge. This translates directly to increased velocity and energy. The increased power also has a noticeable impact on the sound produced.
Factors Influencing Noise Levels
Several factors beyond cartridge type influence the perceived noise level:
- Firearm: The design of the firearm itself plays a crucial role. A firearm with a longer barrel will generally produce a slightly lower report than a shorter-barreled firearm, as the expanding gases have more time to dissipate before exiting the muzzle. The type of suppressor also significantly affects noise levels.
- Ammunition: Even within the same cartridge type, variations in ammunition can affect noise levels. The type of powder and the bullet's construction can slightly alter the sound profile.
- Environment: The surrounding environment significantly impacts the perceived noise. Shooting in an enclosed space will result in a much louder report than shooting outdoors. The presence of sound-reflecting surfaces can also amplify the noise.
Noise Comparison: .22 Short vs. .22 LR
While precise decibel measurements can vary depending on the factors mentioned above, a general comparison can be made: The .22 Long Rifle is considerably louder than the .22 Short. The larger powder charge in the .22 LR results in a more powerful explosion, leading to a significantly higher report.
Think of it this way: The .22 Short is akin to a small firecracker, while the .22 LR is more like a louder, more substantial firework. While neither is excessively loud compared to other firearms, the difference between the two is noticeable to the experienced shooter.
Perceived Loudness: A Subjective Experience
The perceived loudness also depends on individual hearing sensitivity. Some individuals may find the .22 LR noticeably louder than others perceive. The use of hearing protection is always strongly recommended when firing any firearm, regardless of the cartridge used.
Conclusion: Choosing the Right Cartridge
Choosing between the .22 Short and the .22 Long Rifle often depends on the intended use. The .22 Short is generally preferred for quieter plinking or indoor shooting (although it's still essential to use hearing protection). The .22 LR, due to its greater power and accuracy, is a more versatile option for target shooting, small game hunting, and general shooting purposes. However, that versatility comes with the trade-off of a louder report. This difference in noise level, though perhaps subtle to some, should be considered when making your choice.
