Description
The CorBon 357 Mag 100gr PowRBall load is built for shooters who want a proven 357 Magnum round from a company that helped shape modern high-velocity handgun ammunition. Each box holds 20 cartridges loaded with a 100 grain Pow’RBall hollow point bullet rated at 1450 feet per second, producing about 467 foot-pounds of muzzle energy. The Pow’RBall design places a polymer ball in the nose of a hollow point bullet, giving it a rounded profile that feeds smoothly like full metal jacket ammo and drives the hollow point open on impact.
This 357 Mag 100 grain hollow point is the lightest and fastest load in the CorBon 357 Magnum lineup, built for quick expansion with less recoil than heavier magnum loads.

Why Choose the CorBon 357 Mag 100gr PowRBall
- 100 grain Pow’RBall hollow point bullet
- Rated 1450 fps muzzle velocity, 467 ft-lbs energy
- Rounded nose profile for smooth, reliable feeding
- Polymer ball starts expansion even through heavy clothing
- 20 rounds per box, item PB357100/20
Built for Personal Protection
- Carry and home-defense handguns chambered in 357 Magnum
- Shooters who want a high-velocity defensive load
- Practice sessions to confirm point of impact with your carry ammo
- Keeping one consistent lot of ammo in your carry gun and range bag
Before you trust any new defensive load, fire at least 50 to 100 rounds through your handgun to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Rotate your carry ammo every so often, and store the rest in a cool, dry place in the original box so the cartridges stay clean and easy to identify by lot number.
Because a 357 Magnum revolver can also fire 38 Special cartridges, many owners practice with lighter 38 Special loads and then confirm their point of impact with the CorBon 357 Mag 100gr PowRBall before carrying it. Fire enough full-power rounds to get comfortable with the recoil and muzzle blast.

Why Choose CorBon 357 Mag Ammo
Light, fast bullets open quickly and deliver their energy in a hurry. At a rated 1450 fps and 467 foot-pounds, the CorBon 100 grain Pow’RBall gives the 357 Magnum rapid expansion while the lighter bullet reduces felt recoil compared with 125 or 158 grain magnum loads, which helps with control in small and mid-size revolvers.
When you compare 357 magnum self defense ammo, think about how the load performs in the revolver you actually carry. This CorBon load pairs well with the Ruger GP100 and SP101, the Smith and Wesson 686 and J-frame magnums, and lever-action carbines in 357 Magnum. The rounded nose also helps speed reloads with speedloaders and moon clips.
CorBon has built high-velocity defensive ammunition in South Dakota since 1982, when the company set out to solve a common problem: hollow points that plugged with clothing and failed to expand. That focus on real-world performance is still at the heart of every box. Corbon 357 mag ammo is loaded to tight standards so shot-to-shot velocity stays consistent, which helps you build confidence in the same load you train with and carry.
Revolver owners who carry for personal protection or keep a 357 Magnum for home defense will find this load a fast, controllable choice. Always confirm your firearm is chambered for 357 Magnum, wear eye and ear protection, and follow all federal, state and local laws.
