Are 8 gauge shotgun shells larger in diameter than 20 gauge shells?

The answer is that 8 gauge shotgun shells are indeed larger in diameter than 20 gauge shells. This is a fundamental aspect of shotgun gauges; the gauge number is inversely related to the diameter of the shell. A lower gauge number indicates a larger diameter and typically a longer shell as well.

Specifically, the 8 gauge shell has a diameter of approximately 1.05 inches, while the 20 gauge shell has a diameter of about 0.615 inches. This significant difference in diameter means that the 8 gauge shell can carry a larger payload, resulting in greater shot and powder capacity, which is suitable for certain applications such as hunting larger game or for shooting at longer distances.

Understanding the relationship between gauge numbers and shell dimensions is essential for anyone working with shotguns, as it impacts ammunition selection, firearm compatibility, and ultimately safe handling practices.
