The .21 Sharp rimfire cartridge, while less prevalent today than its more famous counterparts, holds a significant place in firearms history. This relatively small round boasts a unique story, from its early development to its niche applications in modern times.

A Look Back at the .21 Sharp's History
Developed in the mid-19th century, the .21 Sharp was a significant step forward in rimfire technology. Its design, while simple by today's standards, was innovative for its time. Unlike earlier rimfires, the .21 Sharp offered improved accuracy and power, making it a popular choice for small game hunting and target shooting. Its use spread relatively quickly, and it enjoyed a period of considerable popularity, particularly in the United States. However, the rise of more powerful and versatile centerfire cartridges eventually led to its decline in mainstream use.

- Velocity: Variations exist depending on barrel length and powder charge, but generally falls within the subsonic range.
While the .21 Sharp's velocity might seem modest compared to modern cartridges, it's crucial to remember the context of its development. In its time, it represented a considerable leap in performance for rimfire ammunition. It offered acceptable accuracy at close to moderate ranges, suitable for its intended purposes.
