Grizzly Cartridge .357 Magnum 210gr FMJ Flat Point

The Grizzly Cartridge .357 Magnum 210-grain Full Metal Jacket Flat Point (Grizzly part no. GC357M20) is a heavy-for-caliber loading from Grizzly, a smaller-batch domestic ammunition maker known for pushing bullet weights past what mainstream factory loads typically offer. At 210 grains, this bullet is significantly heavier than the standard 125-158 grain .357 Magnum loads most shooters are used to, trading some velocity for genuinely deep, straight-line penetration. The flat-point full metal jacket profile does not expand, instead punching straight through, and also feeds reliably in lever-action rifles chambered in .357 Magnum, not just revolvers. This is a load built for penetration-focused shooters, whether for heavy hunting applications or metallic silhouette competition.
