11.15 x 60 R Mauser (Smokeless) Load Data & Reloading Guide

The 11.15 x 60 R Mauser, commonly referred to as the 11 mm Mauser, is a rifle cartridge first introduced in the late 19th century. Originally designed for use in the Mauser Model 71/84 rifle, it represents a pivotal moment in rifle ammunition development marked by the transition from black powder to smokeless powder. This change significantly improved the velocity and efficiency of firearms using this cartridge. While its military use has long since ceased, the 11.15 x 60 R Mauser remains of interest to vintage firearms enthusiasts and reloaders wishing to preserve the historic shooting experience.

The 11.15 x 60 R Mauser is a large caliber cartridge featuring a rimmed design, which is typical of its era, where extraction reliability was prioritized over the sleeker rimless cases favored today. The typical bullet diameter is approximately 11.15 mm, with case lengths reaching 60 mm, which together allows for a substantial powder charge. Although designed during the transition to smokeless powder, original black powder loads necessitated a robust construction suitable for black powder rifles.

Ballistic performance of the 11.15 x 60 R Mauser depends significantly on the loading method. Typical bullet weights range from 300 to 400 grains, offering moderate velocity but enough stopping power for big game hunting. The cartridge delivers moderate recoil, making it compatible with repeat firing in heavyweight traditional rifles. Accuracy can be optimized through careful reloading practices, allowing enthusiasts to tailor both the bullet weight and powder charge.

For reloaders, the 11.15 x 60 R Mauser offers a unique opportunity to experiment with period-consistent reloading recipes or to modernize loads with current propellants for safer performance in structurally sound antique rifles. Brass for reloading can occasionally be found through specialized vendors or reformed from other calibers, while modern reloading tools and dies facilitate a precise reloading process. This caliber remains cherished by those who appreciate historical arms and wish to experience traditional shooting firsthand.
