Hey
P2, I've never seen it around here, so looked it up on the Net.

Looks like a petroleum based gun oil, with the "treatment" feature being the aerosol delivery system. The ad says "Gu
n Oil - Same as Gun Treatment but in liquid form". Probably would be fine for use on muzzle loaders after a good cleaning with soap and water or a cleaning product specifically made for black powder, like Butch's Black Powder Bore Shine.
