Agree with Majic. 231, bullseye and Unique are great for this. One thing I have noticed though, is that a couple tenths of a grain can make the difference between regular and +p pressures with these powders. So be precise.
Theoretically, a slower powder than these can be loaded easily to +p pressures, but I wonder if you will get any benefit from them in snubby barrels. And less burned powder means more of a mess....
But then, I'm not exactly an expert. I have to admit to liking light loads for practice, and haven't tried much in full power loads. I did recently buy some WST, a slightly slower relative of 231, to try for some heavier loads. Don't know when I will get around to actually trying it......
