Cedar Park, TX (July 2025) – Filling a hole in the market while creating new holes in your targets, Black Collar Munitions is excited to announce a super quiet, uniquely affordable, and readily-available subsonic 308 Winchester ammunition offering!
Loaded in brand new brass, the Black Collar Munitions subsonic 308 Win bulk load fires 220 grain copper plated lead projectiles at 1,050 FPS. A very particular gunpowder is used, which optimizes both consistency and sound. When suppressed, this ammo is insanely quiet!
Sold in 100-round bulk packs for under a buck per round, this is the most affordable subsonic 308 ammo on the market. It’s also reliable, accurate, and consistent!
Steve of Black Collar Munitions says:
Supersonic 308 Winchester is about twice as capable as supersonic 300 Blackout, while subsonic loads are effectively identical – exact same projectiles, exact same velocities, possibly even quieter when suppressed. Unfortunately, subsonic 308 has always been a niche loading, typically too expensive to shoot for fun and hard to find in-stock. We set out to change that!
WARNING! We have decided to maximize subsonic performance by loading 220 grain projectiles. TEST WITHOUT A SUPPRESSOR FIRST to ensure projectiles are fully stable through your rifle. This means bullets are leaving ROUND holes in your target. We tested this ammo through four different, 1:10 twist 308 Win rifles from different manufacturers and all completely stabilized these projectiles out to at least 100 yards. It’s fair to say that 1:7 and 1:8 would be ideal twist rates, 1:10 has proven fully sufficient in our testing, and if your rifle has a slower twist rate than 1:10 we’d advise firing at least 10 rounds into a paper/cardboard target at 50-100 yards to ensure all bullets remain stable before attaching a suppressor.
