Have played with just about all the subs. Huge clouds of non odored smoke, mediocre velocity, and that stuff will eat the cases if not cleaned. So then other than being able to trot into about any Walmart and grab a can what's the advantage again?
Blackhorn 209 does well, but the pressures run higher, making case resizing necessary, and if moisture gets into the fouling it forms a mild form of sulphuric acid. That's why they sell a bore cleaner specifically designed for cleaning up after the stuff...
There are a number of smokeless powders that work well if one is simply to lazy to clean up after shooting..
