HSM 3085N Match Subsonic 308Win 175gr Hollow Point Boat Tail 20 Per Box/25 Case
HSM 3085N Match Subsonic 308Win ammunition delivers precision and control for shooters who need to keep things quiet without sacrificing accuracy. Loaded with a 175-grain hollow point boat tail bullet and pushing subsonic velocity, this round is purpose-built for suppressed rifles, hearing protection, and situations where you need reliable performance below the sound barrier. Whether you're shooting a precision rifle at the range or hunting with a suppressed setup, subsonic 308 Winchester rounds let you focus on accuracy and target feedback instead of noise.
HSM ammunition is known among competitive shooters and precision rifle enthusiasts for consistent quality and attention to ballistic detail. The hollow point boat tail design combines match-grade consistency with predictable expansion, making this load suitable for both target work and hunting applications where accuracy matters. At subsonic velocity, you'll notice less recoil impulse and a flatter shooter experience, especially when running a suppressor—ideal if you're building a quiet, practical rifle.
This product ships in a 20-round box, with cases containing 25 boxes (500 rounds total). It's a solid choice for shooters who regularly run suppressed platforms and need ammunition that won't crack the sound barrier or compromise their hearing protection strategy.

Frequently Asked Questions
What does subsonic mean, and why would I choose subsonic 308 ammo?
Subsonic ammunition travels below the speed of sound (roughly 1,125 fps in standard conditions). At 1,020 fps, this round stays subsonic, which means it won't create the supersonic crack associated with normal rifle fire. When paired with a suppressor, subsonic rounds provide quieter shooting, less recoil, and better hearing protection—making them ideal for suppressed rifles, hearing-sensitive shooting, or situations where noise management is important.
Is HSM 3085N Match Subsonic suitable for hunting?
Yes. The 175-grain hollow point boat tail design provides controlled expansion and reliable performance for hunting applications. The subsonic velocity and hollow point characteristics make it effective for medium-range hunting where suppressed performance is desired.
Will this ammunition work in a standard 308 Winchester rifle?
Yes, this is standard 308 Winchester ammunition and will function in any rifle chambered in 308 Win. However, subsonic rounds are optimized for use with a suppressor and deliver their best performance in that setup.
How many rounds do I get in a case?
Each case contains 25 boxes of 20 rounds each, for a total of 500 rounds per case.
