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

    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.
    Let those who are fond of blaming and finding fault, while they sit safely at home, ask, ‘Why did you not do thus and so?’I wish they were on this voyage; I well believe that another voyage of a different kind awaits them.”

    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?
    You won't outvote the corruption.

    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 load both the Barnes and V-max 110’s.
    POI for both (to 100 yds) is close enough for range use/Drills/practice IME.
    The Barnes 110 gr. “Black Tip” has proven quite effective on large Whitetail.
    A true "Gun Guy" (or gal) should have familiarity and a modicum of proficiency with most all firearms platforms.

    We have also been using the factory Hornady Black 110 v-max for whitetail with good results too. Been thinking it might be fun to try subs at archery distances to see what they would do but I would not bet my life on either of them for home defense.

    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.
