Black Horn 209, is it really non corrosive? Use in .45 Cowboy?

[Virginia Gentleman]

Can anyone tell me about this black powder substitute and is it truly non corrosive?  How does it work in a short case like .45 Cowboy?

Above is a home video of me shooting a Webley Mark VI that I've modified to 45 Colt. I tried a can of Blackburn 209 and it worked fine but was much more powerful than I expected.  I used up the can and stopped using it because;  one, it's expensive considering the price per can and volume used, two,  I don't  think it really  qualifies as a black powder substitute - at least it's not allowed in CAS.  It's neither fish nor fowl. 

As far as corrosive,  I purposely left the gun unattended for at least a week and there was no corrosion developing. I cleaned the cylinder and barrel and outside. Some months later it still looked fine.  But when I started to pull the cylinder off,  it was stuck on.  Not exactly corroded or rusty, but caked up with dry fouling.

I've been real happy with Alliant BlackMZ. It's about as clean as Unique.  It cleans up easy with just water. More powerful than real black so a smaller charge can be used.  Makes plenty of smoke, if that's what you're after.  I use it in C45S, 32-20, and 38 Special. Also load shotgun shells and experimented with it in 44 cap and ball.

I am told that Black MZ is APP wearing a different container. Used it, liked it, but
"When the flame if powder toucheth the soul of man it burns exceeding deep*"
and I fear my soul is burned exceeding deep.  Gun Powder for me.

Blackhorn 209 does not smoke enough for SASS. I tried it in the 44 special and Russian.
