I only have experience with WST. Would you guys mind comparing the other two to WST so I can get an idea of how they will be in 9mm. I want to experiment with another powder and I think I have narrowed it down to 231 or WSF. A brief breakdown or description of each would be awesome so I can easily see the differences between them. Things like burn rate, whether they like light/medium/hot loads. Any thoughts/likes/dislikes you have regarding them. Thanks Wanna kill these ads? We can help!
