Is All Powder The Same?
The short answer: not exactly. There are two types of gunpowder currently available on the market: single base and double base. So what’s the difference between the two?
Single base powder contains what is known as nitrocellulose, while double base includes not only nitrocellulose but also nitroglycerin.
Of the two, the double base will probably have more “oomph”. It also burns hotter and dirtier as well. Double base powder is also said to be associated with maximum velocity.
Aside from that, the performance difference between the two is hard to determine.
How to Choose Powder For a 300 Blackout
Before making a final decision on which brand to choose, it's always important to know some of the aspects that will drive you to make a final decision. The important thing is to carefully consider which is more suitable for the 300 Blackout rifles and cartridges you use. With that said, here are some things to consider:
Subsonic or Full Auto?
300 Blackout rounds come in two types: subsonic or full auto. The important thing to consider here is whether the powder is appropriate for the type of rounds that you use. Your cartridges may be loadable or reloadable. Regardless, you’ll need to find a product that is appropriate for your specific round type. To err on the side of safety, don’t mix powders with rounds. For example, don’t use subsonic powder with full auto rounds and vice versa.
Of course, there are those who are on a budget who may shy away from most brands due to price. But there are a bunch available at affordable prices. Performance and overall quality should also be prioritized when looking for the best possible powder that you can afford.
Which Rifle Do You Use?
Another thing to consider is which rifle you're using for your 300 Blackout rounds. Some use AR-style rifles while others use AR-style pistols and even tried and true bolt action, single-shot rifles. It's important to know which rounds you're using for these types of guns so that you're able to find the type that's best suitable for it. Likewise, you shouldn't use a type of powder that is used for bolt action, single-shot rounds in an AR-style rifle.

Cautious Considerations Before Buying Powder
While there are aspects to consider as part of the decision-making process, we also want to remind you of some things to take note of prior to making a final purchase. These pertain to safety issues and concerns that may arise when you’re purchasing powder for your 300 Blackout. They are as follows:
In some states and jurisdictions, it may actually be illegal to purchase or even own gunpowder if you're under a certain age. In fact, the black powder may be illegal not just in the United States, but around the world. That's why most of the powders these days are far different from the black powder of ages past. But, we digress. It is important to double check the laws in your jurisdiction regarding gunpowder before buying it for your own use.
Find a Powder That Fits Your Rounds
As mentioned, there are supersonic and subsonic rounds. It's highly recommended that you find out which rounds you're using before finding a powder that will be compatible with them. Supersonic powder may be too much power for a subsonic and may cause some damage to your gun or pose as a safety risk. Err on the side of caution and never mix one type of powder with a different type of round.
Do Not Overload
Overloading powder into rounds is potentially dangerous. It’s important to note how much powder should go into each round as you load them. If you have any questions or concerns, be sure to consult with some of your fellow 300 Blackout owners for any answers in regards to safely reloading your rounds.
Finding the best powder for your 300 Blackout is no easy task. But so long as you know exactly what you’re looking for, the task may not be as difficult. Please consider the products that we’ve listed above, along with the specifics of what you need to look out for. And as always, practice safe gun usage and also safe reloading practices.
People Also Ask
Of course, this guide would not be complete without throwing in a few frequently asked questions. Be sure to refer to these while you're looking for a powder that will best work with 300 Blackout rounds. Here are the questions that are usually asked by first time buyers:
What Are The Different Types of Gun Powder?
There are two types of gun powder in existence. They are single base and double base. Both contain nitrocellulose, but the double base also adds on nitroglycerin as well.
What is Powder Metering?
The term metering is best described as how consistent the powder is measured. When you often hear about the powder “metering well”, it means that the precision of the powder is much greater than fluctuating measurements.
What is Burn Rate?
Burn rate is a fancy term to describe how fast gunpowder will ignite. This is kind of like comparing gasoline to something flammable like lighter fluid. As gas tends to explode more than lighter fluid, the latter tends to burn slower and longer. The same will apply to gunpowder. An example of this is comparing magnum powder against non-magnum powder. In short, magnum powder is considered the lighter fluid of gunpowders because it tends to burn slower. Of course, you know what that means for non-magnum types. That kind tends to burn faster.
How Does Gunpowder Explode?
Gunpowder consists of explosive elements. Of course, these elements are derived from nitrogen (more specifically, potassium nitrate). Also included are sulfur and charcoal. If it’s lit by a flame, then it will be able to explode, provided it’s in a confined space. If it’s in an open air environment, it won’t be as combustible.
What is Load Density Reloading?
Load density is defined as a calculation that is used to measure case capacity versus bulk density. Case capacity is defined as a measurement that uses fired brass and fills up with water before loading it to a case neck. Powder bulk density is defined as how many grams of powder can be fit in a liter. Reloading is basically using an amount of powder that is measured near precisely to the amount of the load density.
