Fiocchi Range Dynamics 300 Blackout 220gr Sierra MatchKing BTHP ammunition delivers match-grade precision at factory prices—ideal for shooters running suppressed rifles, subsonic builds, or precision rifle work where consistency matters. Loaded at Fiocchi's Ozark, Missouri facility, these rounds pair Sierra's legendary MatchKing bullets with Fiocchi's rigorous quality control, giving you the accuracy reputation of competition ammo without the custom-loader price tag.
The 220-grain Sierra MatchKing hollow point boat tail is engineered for accuracy. Its thick jacket, improved boat-tail design, and long ogive have made MatchKing the standard in precision shooting for decades. At 1,020 feet per second, this subsonic load is purpose-built for suppressed 300 Blackout rifles, staying subsonic even in short barrels while maintaining the bullet construction that serious shooters trust for repeatable groups downrange.
You're getting 25 rounds per box, with 20 boxes per case—500 rounds total. Whether you're dialing in a new can, working up loads for a precision build, or stocking up for extended range sessions, this case quantity makes it easy to maintain a supply of match-grade ammo without breaking the bank. Fiocchi's consistency means fewer variables to chase when you're chasing tight groups.
