Very hard to beat for the price !! If you're looking for a round with some weight behind it in subsonic 300 Blackout, this is the round for you! They are very consistent, very clean, and feed very well. I have never had an issue with this ammo.

I think at this point I've got a couple thousand rounds of S&B 200 Grain through several SBRs. Other than it being a little dirty, no issues with this ammo. Not the most accurate but good enough and I've not had any go supersonic...YMMV
Tom M.
Awesome training ammo for my Daniel Defense 300ISR. The 124 grain also runs well in that weapon and is surprisingly accurate in my Daniel Defense DDM4 V11 chambered in 300 Blackout. Hopefully, prices will come back down soon.

Is SB300BLKSUBA good for training and target shooting?
