I was expecting the W231 to jump about 80 fps with the .431 laser cast Oregon Trail, and it did. I was hoping that the slight reduction from 6.8 grains of Unique to 6.5 grains would drop it back into my supposed sweet spot for the Ruger SA of around 890 - 900 fps, and it did. I was prepared to drop it to 6.4 grains but do not see any need to considering the velocity and the accuracy.
