True, if you load slow powders to magnum levels you won't have a problem, but what if you want a mid-range load? Trail Boss is a solution but outside of that even medium burning powders suitable for lower-power loads are going to leave room for a double charge.

What do you do? Load .44 Russian brass? Give up on the caliber? What about the .45 Colt? Is Trail Boss the only real solution outside of "process improvement"? I just don't think that "load something that fills the case" is always a practical solution.
