.300 Blackout Powders/Projectiles

[endurokids]

What are some good reliable powders and projectiles for the .300 ACC being shot out of a standard AR15 with 16" bbl at sonic/supersonic speeds for hunting deer?
I can do the testing but simply looking for a starting point here.
I do reload various other calibers now.
Thanks in advance!

I prefer H110 and Barnes 110gr or 125gr TNT bullets.

H110 and 125 sst works very good on deer.

N105 is the quietest subsonic powder for 300blk

More so than trailboss, because that powder is stupid quiet? Of course, it doesn’t cycle an AR...

I bought some N110 to try with some 235gr powder coated bullets

Yep more than trailboss.

Depends on the buffer and spring weight and if you have adj gas block.

Thread revival for Supersonic Blackout hunting load info;

Anyone have a pet load for the Lehigh Defense 125gr Maximum Expansion? Intended for deer inside 150 yards, and don’t currently have any powder in my cabinet good for .300BLK. Ideally something that meters well from a Dillon powder drop, but if the general consensus is something else, that’s not a deal breaker. My rifle is a CVA Scout, so I won’t be shooting high volume anyways.

Above suggestions look like H110 is likely my best bet?

H110 and Lil Gun

hi guys I'm new to the 300 blkout sub game. I have a 300 blkout with a 10" 1 in 8 twist pistol length gas system.

I'm wanting to load Hornady 190gr sub x bullets and I'm wondering if anyone has a couple of powder recommendations to start with that will cycle the gas gun and stay below 1050 fps? this will be shot with a 9" dead air sandman L suppressor.

thank you

Check the pinned Subsonic thread in the Reloading Depot for the widest sample of info. That thread technically covers all things subsonic, but most posts since .300BLK’s inception have been .300BLK w/heavies related.

Subsonics - All Calibers

Just found this thread and am looking to reload my first subsonic loads for .308W and .300BO. I am seeing/reading that you guys are crimping your rounds? I've only ever reloaded for precision rifle, hence never crimped. What's the reason for doing that with subs, and is it necessary? I don't...

thanks guys for the info. I'm in the process of waiting for stuff to show up now. I went with Hornady sub x 190gr, CFE BLK powder, cci 400 primers, and starline brass
