Best 300 Blackout Powder for Accuracy
W296 is a fast-burning pistol powder that is popular among reloaders of the 300 Blackout cartridge. It is well-suited for use with heavy bullets and subsonic loads and is known for its consistent performance and low recoil. W296 is a versatile powder that can be used in a wide range of bullet weights, but it is particularly well-suited for use with heavy, slow-burning bullets that require a lot of energy to stabilize. Looking at various load data manuals, W296 was the most accurate on more bullet types and weights than any other powder.
It is important to note that the best powder for 300 Blackout reloading will vary depending a lot of variables. You need to consider the specific rifle, bullet weight, and desired velocity. We also recommended you consult reloading manuals and seek guidance from experienced reloaders to determine the best powder for a particular application.

Most Cost Efficient Powder
Most of the time, when I go to the store, all the powders are generally the same price. Because of that, the most cost efficient powder is the one that takes the fewest grains. Less grains per round usually means it costs less. The most efficient powder in terms of grains per load is 2400 followed by Lil’ Gun, Enforcer, and then H110.
Most Versatile Powder for 300 Blackout
Hodgdon H110 is a fast-burning powder that is well-suited for use with heavy bullets and subsonic loads. I like the H110 for its versatility. I can use it for pretty much all sized projectiles for my 300blk. It also works for most all my pistol loads. It’s not the most accurate or the most cost efficient, but it performs well in both categories. This is the powder I personally usually grab for most of my 300 blackout loads.
