.41 Rem. Mag. Load Data & Reloading Guide

Also known as: .41 Remington Magnum, .41 Magnum, 10.4×33mmR

About .41 Rem. Mag.

The .41 Remington Magnum, introduced in 1964 by Remington Arms and designed with the input of firearms expert Elmer Keith, aimed to fill the gap between the .357 Magnum and the .44 Magnum. It was intended as a dual-purpose caliber for law enforcement and hunting. However, its adoption by police forces was limited, primarily due to heavier recoil compared to existing service calibers.

Technically, the .41 Rem. Mag. features a case length of 1.285 inches and operates at a maximum pressure of approximately 36,000 psi. This cartridge typically uses bullet diameters of 0.410 inches and is commonly loaded with bullet weights ranging from 170 to 250 grains. Its performance balances high velocity and stopping power, making it effective for medium to large game hunting. The 210-grain jacketed soft point is a popular choice for many hunters, delivering a flat trajectory and significant energy transfer.

Ballistically, the .41 Remington Magnum offers impressive energy levels, with velocities often exceeding 1300 feet per second with a 210-grain bullet. This makes it capable of dispatching game such as deer and wild boar with authority. Additionally, the cartridge has gained a dedicated following among target shooters and handgun hunters who appreciate its power and versatility.

Reloaders benefit from the .41 Rem. Mag.'s relatively lower recoil compared to the .44 Magnum, which allows for faster follow-up shots and better control in situations requiring quick succession of fire. The caliber also offers a wide range of bullet weights and types, providing flexibility for custom loads tailored to specific shooting needs, whether for hunting, self-defense, or target shooting. This versatility, combined with generally good availability of components, makes the .41 Remington Magnum an appealing choice for avid reloaders seeking a powerful and adaptable cartridge.
