Accurate 2230, formerly Accurate M-23, is a fast burning, double-base, spherical rifle propellant. This versatile powder was designed around the 223 Remington, but can be used in many small and medium caliber cartridges including the 308 Winchester. 2230 also works well in big bore straight wall cartridges such as the 458 Winchester. The excellent flow characteristics and grain size of 2230 make it ideal for progressive loading.
Warnings from the Manufacturer:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
