Rare bird, that pistol powder. If I didn't have some left over from previous purchases, I would figure people are pulling my leg that it was ever on store shelves at all.
When I go to our local Sportsman's Warehouse on my quest for the Dodo bird, they have rows and rows of empty canisters as a display. They mock me on the way to the gun counter, where they have a hand written list of powders that they actually have available in the back, where I cant see. The empty 8lb jug of Winchester 231 is particularly abusive to me on my way by.
The list usually includes three or four powders. One of them is usually for a 50 caliber machine gun and sometimes there is some stuff that sounds like it was named after an ancient African warrior.
Neither of these will work in my pistols.
Once in a while, I see something I can use in my rifles, and I ask the powder baron behind the counter to go get me a can of his finest. He goes back there and returns with my purchase. I think the ark of the covenant is hidden back there as well. Couldn't say for sure.
