HSM .220 Swift 55gr BlitzKing Ammo, 20-Round Box

HSM .220 Swift 55-grain BlitzKing ammunition (part no. 220SW-1-N) pairs one of the fastest commercial rifle cartridges ever produced with Sierra’s explosive BlitzKing varmint bullet, built by HSM. .220 Swift has held a reputation for blistering velocity since its introduction, and HSM loads it specifically to put that speed to work on varmints and predators. The BlitzKing’s polymer tip initiates rapid, violent fragmentation on impact, a design built to anchor thin-skinned game instantly rather than risk a runner. HSM precision-matches this load’s components to the bullet, giving it the kind of consistency handloaders spend hours chasing.
