When you need controlled expansion and deep penetration from a revolver cartridge, 357 Magnum ammo loaded with Remington’s Core-Lokt hollow point delivers. This 180-grain semi-jacketed hollow point (SJHP) runs at 1080 feet per second out of a revolver-length barrel, generating 466 foot-pounds at the muzzle. Nickel-plated brass feeds smoothly through cylinder and magazine alike, and Boxer primers let you reload the spent cases. Remington has built the Core-Lokt family since 1949, and this handgun variant applies the same bonded-core technology that has accounted for more whitetail deer than any competing projectile line in North America.
Load Profile
The 180-grain bullet weight sits at the heavy end of the 357 Magnum spectrum — most factory loads top out at 158 grains. Extra mass translates to deeper penetration and better sectional density when you punch through hide, muscle, and bone on medium game. Muzzle velocity of 1080 fps keeps recoil manageable in a full-frame revolver while retaining enough energy to reliably expand the hollow point cavity on impact. Nickel-plated cases resist corrosion in humid conditions and cycle more reliably than raw brass in semi-automatic lever guns chambered for 357.
