Custom-grade ammunition from the factory. Built to the tightest tolerances for peak performance rivaling and sometimes surpassing handloads in many guns. Based on the 221 Remington cartridge, the 300 Blackout cartridge loaded by Hornady is being offered in this load as well as both a subsonic load (MidwayUSA #948-223 ) and the 110 grain V-Max (MidwayUSA #195-410) supersonic load. Because of its low recoil, the supersonic load is great for recoil sensitive shooters. Also makes a great short range hunting cartridge! Built for AR-15 type platform rifles, this cartridge is compatible for guns chambered in the 300 AAC Blackout. The patented Flex Tip bullet features an interlocking design that keeps the core of the bullet and the jacket together creating a deeper penetrating, more humane kill. Not only that, they offer controlled expansion, enhanced accuracy and the delivery of flatter trajectories. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
