What twist does that rifle have? I am surprised a long 70gr bullet stabilized at 1,000 FPS.Gyrkin wrote:With 55 grain bullets I got right at 1000 FPS out of a 16" barrel with 4.0 grains of Trail Boss. With 70 grain bullets, 5.6 grains of Trail Boss did the trick. Fired out of a suppressed AR they were scary quiet. They didn't even think about cycling the bolt, but that just made them even quieter.

I've a 1/9" barrel that stabilizes 69gr just fine at 1000 ft/sec.
It's a Contender barrel in .22 Squirrel.

Re: Subsonic 223
Our subsonic 115's in 300 BLK are just as impressive. These are ment for bolt guns but they are still fun to shoot out of an AR.http://youtu.be/zMlOxO-YCkEBucks13 wrote:That is very impressive. Half of the shots, it sounded like the hammer dropped on an empty chamber!
Re: Subsonic 223
Yeah, you're not kidding. Nice work, and thanks for shooting one NOT ON STEEL first. I get frustrated when videos displaying a suppressor shoot on steel every shot, b/c you cannot appreciate how quite the shot actually is hahahaDetroitammoco wrote:Our subsonic 115's in 300 BLK are just as impressive.

The look on the shooters face says it all! Nicely done... and thanks for sharing.Detroitammoco wrote: Awesome rounds, as you can tell by voices in the background crowd pleasers. No sound filters used. Quieter than my pellet gun! http://youtu.be/GjY0oAZXgqw
In a firefight, incoming fire always has the right of way.
