I have never found the need to trim 9mm, 40 S&W or 45 ACP. I have loaded and fired many thousands of them. The magnum cartridges, .357, 41, 44 Mag, etc are a little different. I do trim them on a fairly regular basis. Even 38 Spls on occasion.

There's not much difference in Unique and Accurate #5 from a burning rate perspective. I think they are very close to each other on the burning rate scale.
