Sierra Bullets .25 Cal .257 - 70gr Blitzking 100ct

Sierra Bullets .25 Cal .257 - 70gr Blitzking ammunition delivers precision reloading components trusted by competitive shooters, hunters, and firearms enthusiasts who demand consistent ballistic performance. This 100-round box of hollow-point projectiles is engineered for varmint hunting and target applications where controlled expansion and reliable terminal performance are non-negotiable. Whether you're handloading for a .25-06 Remington or similar cartridges, these Sierra rounds represent the gold standard for match-grade accuracy and dependable construction.

The 70-grain Blitzking design combines a gilded copper jacket with a lead core optimized for rapid, controlled expansion upon impact. With a ballistic coefficient of .189, these projectiles maintain velocity stability across typical shooting ranges, making them ideal for reloaders who prioritize downrange energy retention and flat trajectories. The sectional density of .162 ensures penetration adequate for varmint-class game while promoting the quick energy dump necessary for humane, ethical harvesting. Sierra's quality-control processes guarantee dimensional consistency, reducing ammunition runout and maximizing case life—a critical factor for reloaders managing multiple shooting sessions.

Precision rifle builders and reloaders benefit most from Sierra's Blitzking line when working within the .25 caliber family, particularly in rifles chambered for cartridges like the .25-06, .257 Roberts, and .257 Weatherby Magnum. Handloaders should consult load data specific to their powder charge and primer combination, as hollow-point designs demand careful pressure management to prevent over-expansion or jacket separation. The 100-count box packaging provides practical economy for high-volume reloaders while maintaining the packaging integrity essential for safe, organized ammunition storage and inventory management.
