Sierra 1507 BlitzKing 6mm .243 70gr SBT Spitzer Boat-Tail Bullets - 100 Count
SIERRA BULLETS
The Sierra 1450 BlitzKing .22 cal .224 50gr spitzer boat-tail (SBT) is a purpose-built varmint and small-game round engineered for hunters and reloaders who demand both accuracy and explosive terminal performance. This 100-round pack gives you the flexibility to develop loads tailored to your rifle while maintaining the reliability Sierra has built its reputation on. The BlitzKing line bridges the gap between match-grade precision and field-proven expansion—ideal if you're loading for prairie dogs, ground squirrels, or other small-game hunting where you need a bullet that shoots tight groups and performs decisively on impact.
What sets the BlitzKing apart is its hybrid design: a proprietary-compound tip paired with a thin jacket engineered for rapid, consistent expansion while maintaining the kind of accuracy you'd expect from a Sierra product. The 50-grain weight in .22 cal is optimized for velocities up to 4400 fps, so it pairs well with common varmint cartridges like the .223 Remington and .22-250 Remington. The boat-tail profile enhances ballistic efficiency downrange, which means flatter trajectories and less wind drift—a real advantage at distance or in open country where wind is a factor.
If you reload, the 100-round quantity lets you work up precision loads without committing to bulk quantities. Sierra bullets have long been the choice of reloaders who refuse to compromise between accuracy on the range and performance in the field. This is a bullet that works whether your goal is load development, competition prep, or field hunting.
