I've got a couple of plastic cans of 777 still lying around. I haven't shot it in some time but what was nice is it was AVAILABLE at the local Gander Mountain whereas BP was not. It doesn't like to be compressed which is opposite of BP. It had a "greasy" residue which seems to provide some level of lube (if you want to call it that...LOL). It does clean up very easy with water. Regarding your question about cleanup, I'm very particular about my firearms especially percussion ones. I tend to get on them and clean them up within a few hours of getting home. With 777, my guess is that it would be okay for a couple of days but for BP I would want to get things cleaned up by the next day at the latest. +1 on Balilstol...great stuff!
