HSM 300 Blackout 220gr Sierra MatchKing BTHP Match Ammo 20rd Box

The HSM 300BLK4N Match delivers precision-grade performance for competitive shooters and hunters demanding consistent accuracy from their 300 Blackout rifles. This premium ammunition features Sierra's renowned 220-grain MatchKing Boat Tail Hollow Point projectiles loaded to exacting match specifications.

What Makes This Different

HSM's match-grade loading process ensures consistent powder charges and optimal seating depth for each cartridge. The Sierra MatchKing BTHP design provides superior ballistic coefficient compared to standard hunting bullets, maintaining velocity and reducing wind drift at extended ranges. Each lot undergoes rigorous quality control testing to verify sub-MOA accuracy potential in precision rifles.

Key Features

• Sierra 220-grain MatchKing BTHP bullets for maximum accuracy
• Boat tail design reduces drag and improves long-range ballistics
• Match-grade powder charges for consistent velocities
• Premium brass cases suitable for reloading
• Subsonic velocity ideal for suppressed applications
• 20 rounds per box, 25 boxes per case (500 total rounds)
• Optimized for bolt-action and semi-automatic platforms

This subsonic load excels in precision rifle competitions where accuracy matters more than raw velocity. The 220-grain weight provides excellent stability in standard 1:7 and 1:8 twist barrels while remaining subsonic through most barrel lengths. Hunters appreciate the consistent terminal performance on medium game, while competitive shooters rely on the repeatable accuracy for match conditions.
