What works?

What are some projectiles that work well with the 300 Blk Out besides Barnes and the Hornady SST, 110-120 gr range.
Super-sonic only. I don't shoot subs.

[20X11]

My favorite is the Speer 125 gr TNT.
Only slightly outside you range. If your gun likes 110 gr, the Nosler 110 gr Varmageddon may be for you.

[BobinNC]

Hornady Vmax 110 grain
Nosler Varmageddon 110 grain
Maker Bullets 110 Grain 300 Blackout Tipped Expanding Bullet
Berger 115 grain FBHP
Lehigh Defense 115 grain Controlled Chaos

If your willing to go heavier and still supersonic:

Speer 125 Grain TnT
Speer 130 Grain HP
Speer 150 grain Gold Dot designed for the 300 Blackout Item: 308150BLKGDB

What's your objective?

All I do is hunt hogs. I don't do much target shooting, and I don't go after deer or other game.
For hogs, I use Hornady 110 grain SP bullets. They're a little cheaper than the VMAX, and seem to work as well for my purpose.

Here's a recent video where I took down a 165 Lb hog at 95 yards, and got a pass-through that knocked down the 40 pounder that happened to be in back of it. https://www.youtube.com/watch?v=y5BSYanVkio&t=5s

I shot it quartering sharply away, and the bullet entered the neck and exited the forehead.
