Winchester WST is a smokeless powder developed in the late 19th century by the Winchester Repeating Arms Company. It was one of the first successful smokeless powders and was widely used in rifles and pistols.

Winchester WST is a ball powder, meaning that it is make up of small, uniform balls. This gives it several advantages over other types of powders. It is less likely to produce a muzzle flash and burns more evenly and thoroughly, resulting in less fouling of the firearm.

Winchester WST is also notable for its low recoil. This makes it particularly well-suited for pistols, where recoil can be a significant issue.

Is WST worth it for a 9mm?

WST is much closer to Tightgroup for burn rate. WST is my most used powder for 38spl and 45acp. Unfortunately, Winchester never gave data for 9mm or 40. I tried it in the 9 and worked up to a significant power factor for the USPSA in the 40. You will have to take your own decision if it’s worth it.

What is the difference between Winchester Super Target and Unique Powder?

Sorry for the confusion. I use Winchester Super Target for 12 gauge loads and Unique for 20 gauge loads. I only mentioned Unique powder because I have it on hand for 20 gauge skeet loads.
