Sierra 41 Cal 170gr JHC

The Sierra 41 Cal 170gr JHC is a powerful jacketed hollow-core component bullet designed for magnum handgun hunting and serious hunting applications. Developed for the .41 Remington Magnum revolver cartridge and enhanced in 1984 with Sierra’s renowned Power Jacket, this .410‑inch, 170‑grain bullet delivers rapid expansion, deep penetration, and reliable terminal performance on North American game.

Featuring a sturdy hollow-core cavity beneath a robust copper-alloy jacket, the 170gr JHC promotes fast, uniform expansion while preserving structural integrity on impact. The upgraded Power Jacket design ensures controlled breakup and deep wound channels—providing both stopping power and weight retention. Originally introduced in 1970, this bullet remains a top performer for big-game hunting in magnum handguns.

Engineered to meet the high-pressure demands of the .41 Remington Magnum, the Sierra 170gr JHC performs just as effectively in the .41 Action Express platform. Its design supports reliable feeding and consistent accuracy in revolvers, delivering ethical terminal results on deer, hogs, and similar game. Sierra’s comprehensive reloading data should be consulted for optimal performance in both rifle and handgun configurations.

Manufactured to Sierra’s precise component standards—170.0 grains weight, 0.410″ diameter, and a sectional density near 0.231—the bullet includes a cannelure for secure crimping in revolver frames. Uniform jacket thickness and concentric core alignment ensure repeatable pressures, consistent seating, and reliable shot accuracy in high-velocity magnum loads.

As a component bullet, the Sierra 41 Cal 170gr JHC gives handloaders full control over powder selection, primer choice, and seating depth—enabling customized load development tailored to penetration depth, recoil feel, and terminal effect. It is not factory-loaded ammunition but a premium handgun hunting component, engineered for big-game performance and long-standing reliability in .41-caliber firearms.
