Sierra Sports Master Handgun Bullets .38 cal .357" 158 gr JSP 100/ct

Sierra Sports Master Handgun Bullets in .38 caliber / .357" diameter, 158 grain jacketed soft point (JSP) are engineered for consistent expansion and reliable performance across a broad velocity window. Loaded 100 rounds per box, these bullets deliver the dependable accuracy and energy transfer demanded by handloaders, competitive shooters, and defensive ammunition builders who require precision projectiles without compromise.

The 158-grain weight in a .357" diameter provides moderate recoil control while maintaining sufficient momentum for target penetration and expansion in the .38 Special and .357 Magnum pressure ranges. Sierra's serrated power jacket design on the hollow point cavity controls expansion along the serration lines, promoting uniform mushrooming and predictable weight retention. This design principle matters in duty or defensive loads where consistent bullet behavior across varying targets—from barrier-penetration scenarios to soft-tissue terminal ballistics—directly impacts shot reliability and shooter confidence.

Precision handloaders, law enforcement ammunition manufacturers, and sport shooters building .38 Special wadcutters, semi-wadcutters, or .357 Magnum duty rounds specify Sierra bullets for their dimensional consistency and jacket-to-core bonding integrity. The 158 gr profile is a proven standard for mid-range velocity loads in both snub-nose revolvers and service-length barrels, balancing recoil impulse against consistent expansion performance. A 100-count box suits both small-batch custom loading and mid-volume commercial ammunition production.
