Does anyone make ammo in 5.56 or 300 Blackout specifically designed to burn completely in a short barrel? I'm interested in supersonic, self defense ammo.

Anyone?

Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams

I don’t recall ever seeing ammunition whose factory specifications included burning all the powder in a specific barrel length, but Hornady has a supersonic 5.56mm NATO load that’s advertised as being optimized for short barrels. It’s claimed that it won’t foul suppressors, so that also suggests it does burn more of the powder in short barrels than more common loads.

In general I would expect 300 Blackout loads to burn their powder more efficiently and completely than the 5.56, but I’m just guessing about that.

That's what I ordered, in 110gr 300 Blackout. No mention of barrel length tested but it says optimized for rifle, pistol, and suppressor use. It looks like a good choice for SD ammo.
