The Sierra BlitzKing .25 caliber 70 grain rifle bullet is purpose-built for varmint and small game hunting where flat-base construction pairs with explosive terminal performance and reliable accuracy at extended range. These bullets feature Sierra's proprietary polymer tip and thin jacket design—the same precision engineering found in their MatchKing line—engineered to deliver consistent expansion while maintaining the ballistic stability serious long-range varmint hunters demand.
BlitzKing bullets in .25 caliber fill a specific gap for shooters stepping up from the lighter 20 and 22 caliber options. The 70 grain flat-base configuration offers a ballistic coefficient of .260 when driven at 3150 fps and above, with usable velocity ranges down to subsonic speeds (BC .230 at 1800 fps and below). This velocity flexibility means you can load these bullets effectively across a wider range of .25 caliber cartridges—from moderate handloads to full-power rifle loads—without sacrificing the bullet's designed function.
Whether you're handloading for a .257 Roberts, .25-06, or similar cartridge, the BlitzKing's combination of thin jacket construction and polymer tip delivers the rapid, predictable expansion varmint hunters expect while maintaining the inherent accuracy that makes reloading worthwhile. A box of 100 gives you plenty of rounds to develop a load and spend time at the range dialing in your setup.
| Caliber | .25 cal (.257") |
| Weight | 70 grains |
| Bullet Type | BlitzKing (Flat Base) |
| Ballistic Coefficient | .260 @ 3150 fps+; .251 @ 2800–3150 fps; .242 @ 1800–2800 fps; .230 @ 1800 fps and below |
| Count Per Box | 100 |
| Manufacturer | Sierra Bullets |
These .257" diameter bullets are designed for .25 caliber rifle cartridges such as the .257 Roberts, .25-06 Remington, and similar rounds. Always verify bore diameter and consult your rifle's manual and reloading data before loading.
Sierra makes both a 70 grain flat-base and a 90 grain boat-tail BlitzKing in .25 caliber. The 70 grain offers a flatter trajectory and is better suited to moderate velocity loads, while the 90 grain provides higher ballistic coefficient for longer-range performance. Choose based on your rifle's capabilities and intended hunting distance.
Yes. The BlitzKing line was specifically developed to extend the range of .25 caliber varmint loads beyond what lighter caliber bullets can achieve. The combination of ballistic coefficient, polymer tip design, and jacket construction supports effective long-range accuracy and expansion.
Each box contains 100 Sierra BlitzKing bullets.
