Is there a “go to” powder for subsonic 300 black out? CFE Black is a joke and a terrible powder. You would think a powder that’s designed around the 300 black out would meter better.
Anyway, my buddy uses accurate 1680 and I’ve shot some of his loads and works great. Only problem is, I can’t find it anywhere due to the current situation.



Anyone else have a favorite powder for subsonic 300?
 
Shooters World Blackout is optimized for heavy subs. SW SOCOM is good to run supers and subs. Both stay in stock far longer than the more well known alternatives and seem to pop in stock about every 2 weeks between PV and Midsouth. Just another couple options to throw out there.

Like the others said though, something else is going on if CFE isn't metering well enough.
 
I'm running IMR 4198 under a 220 gr bullet. Has worked well for me in the 10 - 11 gr range, and meters fine out of my Dillon progressive (well enough for semi auto ammo anyway).
 
"A" good powder? For 300BLK? There are dozens of great powders. That's one of the most awesome things about reloading for that cartridge. There is such a wide selection you can tinker around creating loads for years.

In my experience though powder selection depends on the bullet and what the desired end result is. For an extremely quiet load out of a semi auto the best I've found so far is Accurate #9 and a Hornady 225grain bullet.

what do you mean meter better? My CFE meters just fine. The only issue I have with it is it makes a mess because they roll out the spout easy from any breeze or fart when I grab the pan.

Cfeblk will run the action pretty much way lower than what you would think.

Makes it noisy, but a good trade in my book.

1680 is dead reliable too of course for subs.
