Are 8 gauge shells smaller in diameter than 20 gauge shells?

The claim that 8 gauge shells are smaller in diameter than 20 gauge shells is incorrect. In fact, 8 gauge shells have a significantly larger diameter compared to 20 gauge shells. The gauge number system in shotguns is based on the number of lead balls of a particular diameter that weigh the same as the shell. Therefore, an 8 gauge shell, which is larger, corresponds to fewer lead balls fitting into a pound compared to a 20 gauge shell, which is smaller.

Understanding the relationship between gauge sizes is essential for anyone handling shotguns, as it affects not only the type of ammunition used but also the firearm’s handling and firing characteristics. Thus, the idea that larger gauge numbers correspond to smaller diameters is fundamentally incorrect, highlighting that 20 gauge shells are indeed smaller than 8 gauge shells.
