It's what I started loading with back in the very early 1970's and have been using it ever since. 30-30, 35 Remington, 243, 308 Win, 30-06, and some others. I don't use it exclusively, but it's what works the best for me in 30-30, followed closely by IMR 3031. I find that it even performs very well in some cast-bullet applications. As others have said, it meters very nicely through powder measures. this is a very good powder, as is Winchester 760, but it doesn't get much recognition by most of the gunrag writers. It's still in production, and will hopefully stay that way for the rest of my loading lifetime.
