What BP load do you use?

What is 777 like to clean is there any difference in cleaning methods between BP and 777 is 777 as corrosive as Pyrodex.

Can't speak for BP, as I've never used it. 777 seems slightly easier to clean than Pyrodex (but I only used Pyrodex once - about 30 loads). I can't speak from experience, but all I've heard is that Pyrodex is slightly more corrosive than 777 and both are worse than BP. I clean my ROA as soon as I'm home, about an hour after finishing shooting, with hot soapy water and it's straightforward.

With 24gr of 777 what size pre-lubed wad and then what is the depth from face of cylinder to ball. Do you use grease to stop flash over.

I've just done a bit of measuring - the empty chamber is approx 32mm deep, 24gr of 777 fills 16.5mm, the wad is 4mm and I measured a .457 ball at 11.65mm. The ball seats approx 2-3mm below the cylinder face (I'll double check that when I shoot tomorrow night) so everything is snug, with powder and wad compressed by a couple of mm. I don't use grease and have never had a flash over. I fill the chambers from pre-measured glass vials and make sure there are no loose powder grains anywhere else. It works great and is certainly more accurate that me
