It's my favorite 22-250 powder in conjunction with a 55 gr. Ballistic Tip. As previously mentioned, it's not something for getting maximum velocity. I could be getting a couple hundred more fps with other powders but 4320 is so darn accurate and consistent that I keep using it. In my varminting experience with it I don't think a couple hundred fps ever made a bit of difference to any of the woodchucks that "participated" in some of my load development testing projects.
