231 is kind of dirty, anyway it's loaded.
But it's easy to clean off and it also provides consistent velocity, round to round.
Some of the cleaner burning powders are often less consistent and actually harder to get off the gun parts.
There might be less of it to clean, but it requires more elbow grease than 231.
231 is good stuff.
