Has anyone tried loading 223 subs?

I would consider just picking up a 9mm PCC. You can shoot steel, and in normal times, it’s way cheaper to shoot.

Have one, but it's not the same. And they get the rifle FILTHY! I mean failed trigger resets within 200 rounds kind of filthy, and it schmoos up the gas tube and everything, too.

Cleaning rimfire cans sucks, too.

Keyholling would be fine. I just want to shoot steel inside 50 yards.

How do they load such a heavy projectile? I didn't think it was even possible.

You’re not concerned with baffle strikes?

To the dude that suggested a long, heavy bullet: don’t forget about stabilization. Heavy is good, but length is something that has to be considered.

The PCC suggestion is a pretty good one, and I use that for a significant portion of my close range training for the reasons that popped up in this thread, and more. If the goal is inexpensive SBR training that won’t break your ossicles, a PCC is an awesome tool. It’ll never be as quiet as a subsonic small-bore, but its a happy medium that’ll work your timer without being overly loud and expensive. Mine is a very near-clone to my 556 gun, instead of being super short or pimped for USPSA.

Magazine dimensional limits would be my concern with heavy long bullets. I have tried the Atomic subs out of an 18” barrel using a can and no cycling but stupid quiet. I was concerned about the bullet leaving the barrel as well. I think I will stick with .300 blk subs suppressed with pistol length gas. To me there is no point in trying to reload subsonic .223 when there are better options IMO.

I can't imagine a more pointless reloading endeavor.

I quit my reply yesterday trying to think of a diplomatic way to say the exact same thing.

Atomic makes two weights of .223 subs. Which did you use, and did it stabilize?

I have so much money in my setup I can't clone it to another upper. Still kind of the same thing though where it's still just not quite the same. Different mags, different ergos.

What, your training clone would need a MAWL and Nightforce? Now I’m interested for sure.

Wobble inside the suppressor would be a great way to initiate baffle strikes... Just sayin...

I did already mention that my primary goal here is to be able to shoot at night without bothering the neighbors.

And you don't think pistol powders and 'fillers' are going to dirty up your gas tube?
