Fiocchi 300 Blackout 220gr Sierra MatchKing BTHP Subsonic Ammo

The Fiocchi 300BLKMB Range Dynamics delivers precision subsonic performance with 220-grain Sierra MatchKing bullets engineered for suppressed shooting and long-range accuracy. This premium ammunition combines Fiocchi's consistent manufacturing with Sierra's proven boat-tail hollow point design for exceptional ballistic performance.

What Makes This Different

The 220-grain Sierra MatchKing bullet maintains subsonic velocities while delivering superior accuracy compared to standard 300 Blackout loads. The boat-tail hollow point design reduces drag and provides consistent expansion, making it ideal for both precision shooting and hunting applications. Fiocchi's Range Dynamics line uses match-grade components and quality control standards that exceed typical plinking ammunition.
