 If you're using real blackpowder and a good bp lube, there is no corrosion problems, so long as you clean and oil the gun and wash and dry the cases.
 Most of the horror stories about the corrosiveness of real bp is just so much internet reguritation of old wives tales, with no first hand experience to back them up.

In the 1920's "sheeple" was a term coined by the National Socialist Party in Germany to describe people that would not vote for Hitler. In the 1930's they held Hitler as the only one that would bring pride back to Germany and bring the budget and economy back.....

Fluffy, the foul of black powder is primarily composed of potassium bicarbonate and potassium sulfide.  Neither of these compounds WITHOUT ANY MOISTURE will NOT be corrosive.  Rust (corrosiveness) is the chemical reaction of oxygen and iron ... http://en.wikipedia.org/wiki/Rust
Leave an uncleaned BP firearm void of any humidity and it will not rust.  Therefore, there is no less corrosive powder

Or make your own without the sulphur.  ;)  Sulphuric Acid is what is formed when water and sulphur in real bp combine and is why they need to be cleaned properly.  It's nearly impossible to keep a firearm moisture free, but a good lube keeps your bore clear at least.  8)  The only thing the sulphur is in there for is a flash point reducer.  Modern caps and primers shouldn't have any issue with ignition.  Some flinters might.  ;)

It's not the black powder that killed most barrels, it was mostly the mercuric primers they used back then.
Clean your rifle using just plain water or add just a bit of soap in the water and clean the bore followed by a few dry good cotton patches and a oily patch and your done.
If your clean dry patches still have gray streaks on them you will have to work on the lead that is still in there.

Yep, all my black powder guns look new like the day they left the factory. Water to clean, dry off and lube up with Ballistol for storage. The only time I have had corrosion problems is when I tried that horrible  stuff, Pyrodex. That rusted up a nice '73 single action something fierce. I won't touch that stuff again, it's real BP for me.

Hello, everyone.  I gave up on black nearly 20 years ago..discusted with the then available Goex.  Now I am using Swiss...and LOVE it!  Clean-up is very simple..I bought a bottle of Butch's Black Powder Bore Shine..3 wet patches & it's done!  This is in a little .25-25..I was dreading using real B.P. in such a small bore..fouling is not that bad.
