5.56 subs anyone making it?

[maxipum]

Anyone out have a recipe for subsonic 5.56?

Standard velocity .22 Long Rifle. You can even get a kit so that it will cycle in an ar15.

All jokes aside, subsonic 223 is exceedingly hard to accomplish, won't cycle any semi-auto, and is almost, if not completely, pointless.

I have no advice other than finding the heaviest .223 bullet you can, using a pistol powder in combination with a case filler, and being super careful to not let a secondary explosion effect ruin your gun, or you.

Seriously, if you want a subsonic 22 caliber firearm, get a .22 Long Rifle and some standard velocity or sub sonic ammo. Aguila makes a super heavy sub sonic 22lr with a 60gr bullet that some people like.

I’ve made some with 77s and TrailBoss for a suppressed bolt action 223. Definitely more energy in steel than any 22LR...lot more expensive in this age of scarce components, too.

Yea, i call it 300BO. Loves itty bitty barrels too :-)

A guy could probably load 90s backwards, at mag length, thereby:
—taking up quite a bit of the wasted volume;
—enabling stabilization of an extremely high SD bullet, as heavy-for-caliber as possible;
—slowwww down muzzle velocity;
—and increase impact violence by sending what amounts to a very small Keith nose down range.

I would imagine effective BC would still be decent, at SUBsonic speeds.

Whaddaya think avboiler?

I reload 308 subs with trail boss and I love the results. Definitely the wrong time to be hunting components. I appreciate all the responses keep them coming.

I think this sums it up pretty well. Bolt action? Suppressed? There are some better caliber choices for shooting subs, so elaborating on the inteneded purpose might help with a solution.

When I hear Subsonic I think bolt-action

Come to the dark side of 300BLK, suppressed in an AR pistol. With handloads, yes it cycles, yes it's accurate, yes it's movie quiet and yes it's as much fun as you can have with your pants on.

Sounds...expensive if you’re trying Bergers or 95 SMKs! 88 ELD might be an interesting test case though.

Casting your own heavy 22 cal bullets might be a good but cheaper option for subsonic use, especially if you're not using a semi-auto.

But that's a whole new hobby/addiction/expense, and lead is not as cheap as it used to be.

Also, you'd want a supressor you can disassemble for cleaning the lead out. I would think a good supressor rated for 22LR would work just fine for 223 subs. Not much difference between the two.
