This is a spherical (ball) powder known for its clean burning properties, low flash, and minimal smoke. Its fast burn rate makes it a highly versatile powder for both shotshell and handgun reloading. It is an excellent choice for light to medium shotshell loads, where it can be used to duplicate popular factory loads. In handgun applications, WST is a preferred powder for standard velocity target loads in common pistol calibers like .45 ACP, 9mm, and .38 Special. The powder's consistent metering from its spherical shape is a key advantage for reloaders, ensuring uniformity and accuracy.
