.27 Long: A Comprehensive Overview

The .27 Long is a rimfire cartridge that was developed in the late 19th century. It was designed for use in small game hunting and target shooting, offering a balance between power and low recoil. Despite its initial popularity, the .27 Long has become largely obsolete in modern times, replaced by more efficient cartridges.

History and Development

The .27 Long was introduced in 1890 by Stevens Arms Company. It was designed as an improvement over existing rimfire cartridges of the time, offering slightly more power while maintaining the low recoil characteristics that made rimfire cartridges popular for small game hunting and target shooting.

The cartridge was primarily used in single-shot rifles and some early repeating firearms. It gained a following among small game hunters and target shooters who appreciated its accuracy and mild report. The .27 Long was particularly favored for shooting gallery use, where its low recoil and relatively quiet report made it ideal for indoor shooting ranges.

Despite its initial popularity, the .27 Long began to decline in use by the early 20th century. The introduction of more powerful and versatile rimfire cartridges, such as the .22 Long Rifle, began to overshadow the .27 Long. Additionally, advancements in centerfire cartridge technology provided hunters and shooters with more powerful options that could be easily reloaded.

By the mid-20th century, production of .27 Long ammunition had largely ceased, and the cartridge became obsolete. Today, it is primarily of interest to collectors and firearms historians, with original ammunition being rare and valuable to collectors.

Technical Specifications

The .27 Long cartridge features a rimfire priming system and a straight-walled case. It typically used a lead bullet with a diameter of .275 inches. The cartridge's overall length is 1.175 inches, with a case length of 0.815 inches. The standard load for the .27 Long consisted of a 40-grain lead bullet propelled by 10 grains of black powder, achieving a muzzle velocity of approximately 1,000 feet per second.
