Sierra BlitzKing 6mm rifle bullets deliver the flat-shooting, explosive performance you need for varmint and small-game hunting. These .243-inch, 55-grain projectiles combine Sierra's legendary accuracy reputation with a design built for fast-expanding terminal performance. The proprietary polymer tip and thin jacket work together to ensure consistent, devastating expansion while maintaining the precision you'd expect from a company that's built its name on match-grade ballistics.
BlitzKing bullets are engineered specifically for the velocities you'll push them to in the field. The 55-grain 6mm variant is rated for muzzle velocities up to 4000 fps, giving you room to load them in a wide range of .243 Winchester and 6mm Creedmoor rifles without worrying about jacket separation or over-expansion at the muzzle. That velocity ceiling also means they'll remain stable and consistent whether you're running them through a bolt gun or an AR platform chambered in 6mm.
Each 500-count box gives you enough ammunition to develop your loads, dial in your rifle, and spend serious time in the field or on the range. Whether you're prairie-dog hunting out West, targeting coyotes, or zeroing in your varmint rifle for precision work, Sierra BlitzKing bullets offer the performance consistency that's made the brand a standard among reloaders and shooters who refuse to compromise on accuracy.
| Caliber | 6mm (.243") |
| Bullet Weight | 55 grains |
| Bullet Diameter | .243 inch |
| Bullet Type | BlitzKing (varmint/small-game) |

| Manufacturer | Sierra Bullets |
These .243-inch, 55-grain BlitzKing bullets are designed for 6mm and .243 Winchester rifles, as well as other 6mm cartridges like 6mm Creedmoor. Always verify bore diameter and twist-rate compatibility before loading or firing.
BlitzKing bullets are purpose-built for varmint and small-game hunting. The thin jacket and polymer tip are designed for rapid expansion on lightweight game, making them ideal for prairie dogs, coyotes, rabbits, and similar targets.
Sierra rates the 55-grain 6mm BlitzKing for maximum muzzle velocities up to 4000 fps. Exceeding that velocity risks compromising jacket integrity and expansion performance. Always start at a lower velocity and work up when developing your loads.
Each box contains 500 bullets, giving you plenty of rounds for load development, practice, and field use.
