Atomic Ammunition 6.5 Creedmoor Subsonic 130 Grain Sierra GameKing HPBT rounds bring specialized performance to hunters and shooters who need subsonic velocity without the crack. The 6.5 Creedmoor platform has earned a reputation for precision and versatility, and subsonic loads unlock new tactical possibilities—whether you're hunting with a suppressor, practicing at the range without disturbing neighbors, or working in low-light scenarios where ballistic performance at reduced speed matters. The 130-grain Sierra GameKing hollow-point boat-tail bullet is engineered for controlled expansion and deep penetration, making these rounds a solid choice for medium-game hunting or precision rifle work where subsonic ballistics make sense.
What sets subsonic 6.5 Creedmoor apart is the engineering challenge it represents. Staying below the sound barrier while maintaining bullet stability and energy demands careful powder and load management. Atomic's subsonic offering puts that work in the box for you—no handloading guesswork required. The 130-grain GameKing profile balances bullet weight and aerodynamics for consistent velocity from subsonic loads, which is critical if you're using a suppressor and want the sound signature to stay truly quiet.
Each box contains 20 rounds, a standard quantity for most shooters who want to test a load, zero in subsonic ammunition, or practice without burning through a case at a time. If you're running a suppressed 6.5 Creedmoor for hunting or tactical use, or exploring what subsonic performance looks like in a modern cartridge, this is worth a magazine's worth of testing to see how it performs from your rifle.

Subsonic ammunition is loaded to travel below the speed of sound (approximately 1,125 fps depending on altitude and temperature). While a suppressor amplifies the benefits by eliminating the supersonic "crack" you'd hear from normal loads, subsonic ammo still works in any 6.5 Creedmoor rifle. You'll just hear the action and suppressor signature, not a loud report. Many shooters use subsonic loads for hearing protection and neighbor courtesy even without a can.
Yes. Any rifle chambered in 6.5 Creedmoor will chamber and fire subsonic rounds. The subsonic designation refers to the powder charge and velocity, not the case or headspace. You may notice slightly softer recoil and different point-of-impact compared to standard-velocity loads, so plan to test and zero accordingly.
The GameKing is a hunting-oriented hollow-point boat-tail bullet engineered for controlled expansion on medium-sized game and predictable performance. The hollow point initiates expansion while the boat tail helps with aerodynamics and stability, particularly important in subsonic loads where velocity is lower.
This product comes in a 20-round box, a practical quantity for shooters who want to test a new load, zero in their subsonic setup, or conduct practice sessions without committing to full case quantities.
