Grizzly Ammo centerfire handgun cartridges are engineered for maximum penetration and structural integrity. These 357 Mag rounds feature a 148 gr Full Metal Jacket Flat Point (FMJFP) projectile, achieving a powerful muzzle velocity of 1550 ft/s. The flat point design ensures straight, deep penetration through brush or heavy bone without deforming prematurely. Each box contains 20 rounds of high-performance ammunition. Delivering approximately 790 ft-lbs of energy, this load is an ideal choice for woods carry, training, and target shooting where expansion is not required. Safety Note Always verify your firearm is specifically chambered for 357 Mag. This FMJ load will over-penetrate in urban environments; always maintain a safe muzzle direction and be aware of your target and what lies beyond it.
