Sierra 38 Cal 140gr JHP

The Sierra 38 Cal 140gr JHP is a high-performance jacketed hollow-point component bullet designed for handloaders and hunters who demand reliable expansion, deep penetration, and consistent accuracy in .38 Special and .357 Magnum platforms. Featuring a .357‑inch diameter and 140‑grain weight, this bullet from Sierra’s SportsMaster line delivers controlled terminal performance across revolvers and rifles.

Constructed with a robust copper-alloy jacket and a precisely engineered hollow‑point cavity, the 38 Cal 140gr JHP offers rapid and reliable expansion at typical defensive and hunting velocities between 1,000 and 1,400 fps. The deep cavity and Power Jacket skiving ensure uniform upset and broad wound channels while minimizing fragmentation—making it suitable for varmints and medium-sized game.

Manufactured to Sierra’s strict component standards—140.0 grains weight, 0.357″ diameter, and a sectional density near 0.157—the bullet includes a cannelure for consistent crimping in tubular-magazine or revolver cartridges. Uniform jacket thickness, precise meplat geometry, and tight concentricity support smooth feeding, stable chamber pressures, and repeatable shot placement.

Optimized for both revolver and rifle platforms, the 140gr JHP performs exceptionally at velocities from 1,000 to 1,600 fps. Handloaders report reliable cycling in revolvers and carbines alike, with sub‑MOA accuracy achievable in well-developed loads. The design offers dependable expansion and penetration on predators and defense scenarios.

As a component bullet, the Sierra 38 Cal 140gr JHP gives reloaders full control over powder selection, primer choice, and seating depth—allowing tailored load development for desired trajectory, recoil management, and terminal effectiveness. It is not factory-loaded ammunition but a purpose-built JHP component intended for consistent, ethical performance in .38/.357 applications.
