Atomic Ammunition 308 Win Subsonic 275gr Round Nose - 20 Rounds

The Atomic Ammunition 04966 Rifle Subsonic 308 Winchester delivers heavy 275-grain projectiles at reduced velocities for suppressed shooting applications. This specialized subsonic load maintains terminal performance while operating below the sound barrier for maximum noise reduction.

What Makes This Different

Unlike standard 308 Winchester loads that produce supersonic crack, this subsonic ammunition stays below 1,100 fps to eliminate the sonic boom. The heavy 275-grain round nose bullet provides exceptional penetration and energy transfer at reduced velocities. Atomic's precision loading ensures consistent performance shot after shot, with velocity variations typically under 15 fps standard deviation.

Key Features

• 275-grain round nose bullet optimized for subsonic velocities
• Muzzle velocity approximately 1,050 fps for reliable cycling
• Premium brass cases with consistent powder charges
• Designed specifically for suppressed rifle applications
• Compatible with standard 308 Winchester chambers
• 20 rounds per box, 10 boxes per case (200 total rounds)
• Round nose profile ensures reliable feeding in semi-automatic rifles

This ammunition excels in hunting applications where noise reduction is critical, tactical operations requiring stealth, and recreational shooting with suppressors. The heavy bullet weight maintains downrange energy despite the reduced velocity, making it effective on medium game at appropriate distances. The round nose design feeds reliably in AR-10 platforms, bolt-action rifles, and other 308 Winchester firearms.
