Black Mag 3 is not really a
new powder... it was originally marketed by chemist Dr. Anthony Cioffi (developer of the formula) through his firm ARCO Powder Co. based in Florida.
I tried it at the time, about ten years ago, and was
SO pleased I stocked up wholesale at that time and still have a small amount of the original.
MagKor, the current manufacturer of Black Mag 3 has, according to tests by a few sources I've seen, retained all the properties of the original if not enhanced them.
This is their website:

They are affiliated with MDM in Maine.
There is contact info and one listing for availability:

I cannot stress enough how clean and easy to use this stuff is.
I discharged my rifle after a fruitless season several years ago, brought it home and put it in the back of a closet with intentions of cleaning it the following day... :?
completely forgot about it for several months!
When I finally did remember, hauled it out and inspected the bore expecting a nightmare! :shock:
All I discovered was the same fine, gray burned powder residue left when freshly shot!
Cleanup was as routine as always.
At present the entire MagKor supply is being used to assemble those
cartridge doodads MDM is hawking, but loose powder is supposed to be available soon. Rumor is it will be kinda' expen$ive($40.00/lb.) but is so superior to ALL the others I've tried in terms of user friendliness both at the bench and during cleanup, I for one will not be put off by the stiff price.
