| .357 | 9.07 | Revolver |
Understanding these measurements allows you to make informed choices about your firearms and their compatibility with ammunition. Always guarantee that you’re using the correct caliber for safety and performance.
How Gauge Is Measured
When measuring gauge, you’ll notice it differs greatly from caliber, as it’s based on a standardized system related to the number of lead balls that fit within the barrel. Understanding these measurement standards is essential for comparing various gauge sizes accurately. In this section, we’ll explore how gauge is quantified and highlight common sizes you’ll encounter.
Measurement Standards Explained
Although gauge measurements can seem perplexing, they play an essential role in distinguishing the size of shotgun and certain other types of ammunition. Gauge is determined by the number of lead balls of a specific diameter that weigh one pound. The smaller the gauge number, the larger the diameter of the bore. Here’s how it breaks down:
- 12 Gauge: Commonly used for hunting and sport shooting.
- 20 Gauge: Lighter and often preferred by smaller shooters.
- 16 Gauge: A versatile option between 12 and 20.
- 28 Gauge: Typically used for upland game birds.
- .410 Bore: Technically not a gauge but a caliber, used for small game.
Understanding these standards helps you choose the right ammunition for your needs.
Gauge vs. Caliber Comparison
Understanding the difference between gauge and caliber is essential for anyone involved in shooting sports or hunting. Gauge refers to the diameter of a shotgun bore, measured by the number of lead balls of a specific diameter that equal one pound. For example, a 12-gauge shotgun bore can fit 12 lead balls of that diameter weighing one pound each. Conversely, caliber measures the bullet’s diameter in inches or millimeters, primarily for rifles and handguns. For instance, a .45 caliber bullet has a diameter of .45 inches. While gauge is an inverse measurement, where a higher gauge number indicates a smaller bore, caliber is a direct measurement of the bullet size. Understanding these distinctions helps you choose the right firearm and ammunition for your needs.
Common Gauge Sizes
Gauge sizes are standardized measurements that indicate the diameter of a shotgun’s bore. The gauge is determined by the number of lead balls of a specific diameter that weigh a pound. Here are some common gauge sizes you’ll encounter:
