Swift Zephyr Features The Swift Zephyr bullet is built as a 175 grain 7mm caliber projectile with a .284 bullet diameter giving reloaders a proven option for their 7mm cartridge handloads. Its boat-tail pointed soft point profile is designed to balance a favorable ballistic coefficient of .647 with reliable expansion on impact a combination that benefits hunters chasing medium to large game at extended ranges. A density figure of .310 reflects the bullet s construction and contributes to consistent weight retention as it travels downrange helping preserve energy transfer at the moment of impact. Because this is a component bullet reloaders control seating depth and case prep to fine-tune accuracy for their specific rifle tailoring the load to their own barrel and chamber rather than relying on a factory-loaded round. Packaged in a box of 100 projectiles the Zephyr line gives handloaders enough bullets to work through load development and settle on a final recipe without running short. This bullet is intended strictly for reloading and is not a loaded cartridge so it must be seated into properly prepped brass with an appropriate powder charge and primer matched to the 175 grain weight. The pointed boat-tail design also aids consistent feeding through a variety of rifle actions during the reloading and testing process and the .647 ballistic coefficient helps maintain a flatter trajectory at distance once the load is dialed in. For 7mm shooters focused on long-range accuracy and terminal performance the Swift Zephyr 175 grain bullet is a dependable choice for serious handloading and repeatable results at the range or in the field.
