Sound up. I set my phone at the 100 yard target. Firing the MIGHTY .300 blackout. First two shots are my 230 grain Lee mold cast bullets, at around 900 FPS iirc. Last was a 130 Speer at around 2000. Side note. It’s crazy how well the camera picked up the audio of me racking the bolt.

Two subs were just left of the black dot, the super you can see hit way at the top

Managed a 2” group out of them. Not a single chance I’ll complain about that. Since it’s an AR pistol, it’s not the most conducive to bench work. But hell, it’s STILL a two inch group. I want to play with them at greater distance. At least as far as I have scope adjustment. They were 2 feet lower than the super sonic load zero.

What powder are you using?

Trail boss for subs, H110 for not subs.

Same here. Trail boss has become my goto for almost every sub load.

There’s one using h110, I MAY try just because. Try and get some more speed, push the limits of the sound barrier.
But. Pfffft.


Pffft is the sound the TB loads make.

Once I get my .300 bolt gun built, I’ll play more. The AR pistol is my one trick pony. Late “alternative methods” deer season, using 110 grain Barnes. Not worth farting around with.
Bolt gun though, I’ll have zeros for whatever and be able to just crank the scope.
Want to shoot deer? Cool.
Want to shoot squirrels? Cool.
Want to roam around at night shooting armadillos, possum, and other vermin? Cool.

I use either L'il gun or the original AA2200 for my subs

Chris, barrel length on pistol? And brand if you care to share.
