I've had good luck with it in .357 and .44 Magnum. I haven't tried it in any other calibers as WWB, Blazer Brass, or S&B are typically easier to find and/or less expensive in my area, but I wouldn't hesitate to use it for range fodder if I found a good deal on it. A former acquaintence of mine did have some jamming problems with their .40 S&W 180grn FMJ in his Glock 22, but he had similar problems with Federal Hyda-Shoks and Remington Green box 180grn FMJ so I'm inclined to think that it was either him or the gun rather than the ammo.
