Sierra 38 Cal 158gr JHC

The Sierra 38 Cal 158gr JHC is a precision component bullet designed for handloaders and hunters seeking controlled expansion, deep penetration, and consistent accuracy in .38 Special and .357 Magnum platforms. Featuring a .357‑inch diameter and 158‑grain jacketed hollow-core design, this bullet offers reliable terminal performance in revolvers, lever-actions, and carbines.

Constructed with a sturdy copper-alloy jacket and hollow-core cavity, the 158gr JHC promotes gradual, uniform expansion—producing effective wound channels while retaining mass for deep penetration. The design ensures structural integrity at velocities between 900–1,400 fps, making it suitable for medium-game, defensive applications, and range use.

Manufactured to Sierra’s tight component standards—158.0 grains weight, 0.357″ diameter, and a sectional density near 0.177—the bullet features uniform jacket thickness, precise meplat alignment, and concentric construction. A cannelure ensures secure crimping in revolver-cylinder or tubular-mag platforms, contributing to repeatable chamber pressure and shot performance.

Optimized for handgun and rifle velocities between 800 and 1,600 fps, the 158gr JHC delivers dependable accuracy and penetration. Handloaders report consistent feeding, stable shot placement, and effective terminal energy in both defensive and outdoor hunting contexts.

As a component bullet, the Sierra 38 Cal 158gr JHC gives reloaders complete control over powder selection, primer choice, and seating depth—allowing tailored load development for recoil management, trajectory demands, and penetration needs. It is not factory-loaded ammunition but a premium JHC component built for precision and dependable performance in .38/.357 applications.
