Cool score - never seen any. I understand it was a popular powder in the day.
This powder is the Scot brand. I'm from VA. and on Vacation in Maderia Beach Fla. Found this powder in a shop in Clearwater.Keep in mind that there are at least 2 generations of Nitro 100: Scot Nitro 100, Accurate Nitro 100 (dunno if this is the same or diff from the Scot branded powder), and Accurate Nitro 100 NF (new formula).
Make sure you find the right data for the powder you have.
