There are two types of powder on the market today, single base and double base. Both types contain nitrocellulose, but only double bases also incorporate nitroglycerin. This gives it greater power overall, which is usually a good call when working with a 300 Blackout rifle. When you decide to purchase powder for your 300 Blackout, you’ll first need to know if you have a subsonic or fully automatic firearm. You need to have a powder that’s compatible with your cartridges and round type.

Also, if you’re on a budget, price could come into play. Make sure you can find the best bang for your buck, and don’t let yourself overspend. Are you using a rifle or a 300 pistol? Do you have a bolt action, single shot rifle? All of this matters as you choose your powder, since it doesn’t make sense and might even be unsafe to use, for example, powder meant for an AR-style rifle in a single shot mechanism.
