Are All 300 Blackout Powders The Same?

No. There are 2 types of gunpowder available on the market currently: single base, and double base, so what’s the difference between the two?

Single base

Single base powders contain nitrocellulose, which does not burn as hot and as dirty as double base powders.

Double base

Double base powders contain nitrocellulose and nitroglycerin, which makes it burn hotter and dirtier. If you want maximum velocity from your .300 Blackout round, a double base powder is what you would want. Besides that, there’s not much difference between the 2.

How To Find The Best Powder for 300 Blackout

Subsonic or full auto?

.300 Blackout rounds come in 2 forms: subsonic or full auto. The most important aspect here is to consider whether the powder is appropriate for the type of round that you will be shooting.

Regardless of whether your cartridges are loadable or not, you will need to find a product that is compatible with your .300 Blackout round. You don’t want to use subsonic powder with full auto rounds and vice versa.


You should always buy according to your budget. Not all great powders come at a higher price, there are also a bunch that’s just as good but at an affordable price tag. That said, your number 1 priority when looking at affordable powders should be its performance and overall quality so you won’t end up regretting your decisions.

Rifle selection

Yes. you have to take into consideration of the rifle you are using. While some use AR-style rifles, others would opt for AR-style pistols.

It is essential to know what rounds you’ll be using for these types of guns so that you can find the best 300 Blackout powder that’s best suited for it. You wouldn’t want to use a bolt-action powder on an AR-Style rifle.
