Home Forums Hunting & Shooting AR and Tactical Rifles Super sonic 300 BO Loads?

I will be acquiring a Noveske 300 BO upper very soon but won't be getting the suppressor with it. I realize that I may be behind the times, but who has a supersonic load for the Black Out? I can find an abundance of subsonic loads but haven't found too much for super.

I hope to start out fast and eventually explore the subsonic and suppressed loads when I can afford a can.

I am sitting real good with H4895, Tac, and Varget. I also have a few pounds of 2520 but I expect that will be too hot for the 300.

I use Lil Gun, H110, and 1680, with 110-125gr bullets.

All the powders you listed are too slow for the BO.

All my supersonic loads are with the lighter bullets, 150's & up are all subsonic.

Wow! How did I miss that one? Thanks for the link.

Interesting, though OT, I can't see much of a use for the BO, unsupressed, if I"m going supersonic, there are lots better choices, IMHO.

Good luck. A buddy does the same, runs the 110 Barnes in the round.

The 300BLK is a ton of fun to shoot subsonic, super sonic and both suppressed and un suppressed.
The versatility and the fun factor make the 300BLK a joy to shoot.
While there are better tools for specific jobs, the BLK is very well rounded.
I have several AR-15's and the BLK is the one I use the most.
