Blue Dot is my exclusive powder of choice for 10MM, 357 SIG and .40 S&W. Best accuracy and performance is achieved with it in these calibers. I have yet to have a split .40 S&W case or guppy belly bulge with a modest yet factory like 7.1 grains over a 180 FMJ grain (flat nose). I'll keep using it for what I use it for. .40 S&W is a tricky caliber to reload. I don't have any problems with Blue Dot in it.
