What is the best combo of 300 BLK plinking and self-defense subsonic?

[The Dumb Gun Collector]

Hey guys,


In my 556 guns I typically keep 77otm and plink with 55 grain. They have enough overlap where it is fine.

Is there a similar combo in 300BLK? I want to keep it subsonic. I am running a DD PDW with either my harvester 300 BLK or maybe even my pbs wolverine can.

Basically, I am looking for a reasonable target round and self-defense round that have similar trajectories.

Subsonic trajectories won’t really vary much at all.

The big problem is that there isn’t any subsonic I would choose for self defense.

Unfortunately, this ^. My suppressed .300blk SBR is my go to for home defense. It's zeroed for Barnes 110gr black tips, and I typically plink with 145-150gr FMJs. When I shoot subs, there is a pretty significant POI shift, but I make note of it and adjust. Subs are mostly just for fun range use, so I'm not concerned with the POI shift.

What is a good self defense/home defense load for 300 Blackout?

The 110gr Barnes Tac-TX is the best performing load but is very expensive.

The Hornady 110gr Vmax is a good performer at a more reasonable cost.

This. These are the two I stick with. I prefer the Barnes, but if I can't find it, I have no qualms going with the Hornady Vmax.

I've been tempted to pick up some of this, but I'm sitting on almost 2 cases of the Barnes 110 grain magic slayer ammo. Still, I'm tempted.

Unfortunately I don’t trust the Hornady or any load that is significantly shorter than magazine length. Rough handling can cause a round to shift forward enough to jamb up the magazine.

Does this include PMAG 300BLK?

Especially with 300 mags. Those are made with more clearance at the front rib for loading heavy subsonic bullets longer without pigeon toe.

There isn’t a 300 magazine that I know of with a rib at the case shoulder to prevent a short OAL round from moving forward. I don’t know if that’s because nobody making mags understands this or if there isn’t enough shoulder on the 300 for a rib to work.

The best solution at this time is to use ammo with the longer 300 specific bullets loaded to mag length. Like black tip.
