This carefully engineered subsonic load represents the intersection of precision and practicality for the modern shooter. HSM has paired a 175-grain Sierra Hollow Point Boat Tail bullet with a subsonic powder charge, creating ammunition that performs exceptionally well in suppressed rifles while maintaining the accuracy standards demanded by serious marksmen.
Key Features
- Bullet: 175-grain Sierra Hollow Point Boat Tail (HPBT)
- Velocity: Subsonic (below 1,125 fps for reliable suppressor operation)
- Application: Suppressed rifles, precision target shooting, tactical use
- Accuracy: Match-grade consistency for demanding shooters
Performance Characteristics
The reduced velocity of subsonic ammunition eliminates the supersonic crack that occurs when a bullet breaks the sound barrier. This makes suppressed rifles genuinely quiet—a significant advantage for training, hunting, and tactical applications where noise discipline matters.
The 175-grain Sierra bullet is a proven performer in precision shooting circles. Its boat tail design minimizes drag and promotes stable flight, while the hollow point construction ensures reliable performance downrange.
Ideal For
Shooters who have invested in suppressed 308 rifles will find this ammunition delivers the quiet operation their equipment promises. Precision shooters appreciate the match-grade consistency, while tactical practitioners value the combination of accuracy and noise reduction.
Each box contains 20 rounds, with 25 boxes per case for those who shoot regularly.
