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.
Black Collar Munitions 220 grain subsonic 308 Win bulk ammo is in-stock and ready to ship! Find out more at the Black Collar Munitions website here.
NOTE: This subsonic ammunition will not cycle most semi-auto firearms.
‘…very particular gunpowder…”
Say, does this mean that Trail Boss is back in distribution? Would make a lot of guys happy…
Unfortunately no… Trail Boss and similar powders remain unobtanium. At SHOT we were teased that Trail Boss may make a very limited reappearance this year but it was never confirmed and as far as we know never materialized. So we made do with the best we could find and we are quite pleased with the results!
