CorBon Self Defense .357 MAG 140 Grain JHP ammunition is built for shooters who demand reliable performance when it matters most. This 20-round box of 140-grain jacketed hollow point rounds brings together proven design and consistent manufacturing—the kind of defensive load that has earned CorBon a reputation among serious handgun users. Whether you're stocking your carry gun, building a defensive reserve, or training with loads that match your duty round, this .357 Magnum offering delivers the kind of confidence that comes from ammunition engineered specifically for stopping power.

The 140-grain hollow point design combines internal and external serrations with a soft lead cavity to promote controlled expansion on impact. This engineering approach is aimed at achieving the penetration depth needed for reliable performance in defensive scenarios, with typical penetration falling in the 9- to 15-inch range in ballistic gelatin testing. That balance between expansion and penetration is the hallmark of CorBon's approach to self-defense ammunition—stopping power built on physics, not hype.

CorBon rounds are manufactured to exacting standards and loaded fresh, so you're getting ammunition that performs the same way shot after shot. The 20-round packaging makes it easy to keep your defensive guns fed without overbuying, and it's practical for shooters who rotate and maintain their carry loads regularly.
