Recently bought a lot of powder and primers from a widow.I know the guy was a safe reloader(a friend of one of my closest shooting buddy).But I got puzzled when I came in onto a can full of C300 powder.Up to now,I've found only 1 reference to it,stating that it was manufactured here in Canada(Québec)and that the burning rate was somewhere between Red and Green Dot.
Since I like to have criss cross reference and I thrust the old names who are posting here,I'd like to know if anybody here knows anything about that C300.
