Sierra Sports Master .357 125 JHP Ammunition - 100 Rounds (Model 8320)

Sierra Sports Master .357 125 JHP bullets deliver the controlled expansion and terminal performance that handloaders rely on for hunting, self-defense, and target work. Each box of 100 rounds gives you premium handgun bullets engineered to expand reliably across a broad velocity range—a critical advantage when you're working up loads or shooting at varying distances. The 125-grain weight in .357 caliber is a time-tested choice for both magnum and standard .357 applications, offering a balance of velocity and energy that works across common revolvers and semi-automatic platforms.

What sets Sports Master bullets apart is the serrated power jacket design on these hollow-point projectiles. When the bullet impacts downrange, the serrations guide uniform expansion along predictable lines, maximizing energy transfer to the target while maintaining bullet integrity through the weight retention you need for penetration. This consistency matters whether you're handloading for practice, hunting medium game, or defensive purposes—you get reliable, repeatable terminal performance without the guesswork.

Reloaders choose Sierra for the quality control and material standards that back every component. With 100 bullets per box, you've got enough volume for serious handloading without excess waste, making this a practical choice for shooters who want to fine-tune their loads and understand their ammunition from the ground up.
