Cor-Bon Self-Defense .357 Magnum ammunition (brand part no. 357125) drives a 125-grain jacketed hollow point (JHP) to a rated 1450 fps, giving revolver owners a serious personal-defense load built around speed and controlled expansion. Cor-Bon skives and scores the bullet jacket so it opens quickly on contact, then loads it over flash-suppressed powder that keeps muzzle blast from blinding you in a low-light encounter. The combination of high velocity and a jacket engineered to peel back evenly is meant to transfer energy fast while limiting how deep the bullet drives. For a carry or nightstand .357 Magnum, this is a load built specifically for the fight, not the range.
