magpro question

[Lloyd Smale]

along with all the surplus I inherited I got a 8lb jug of aa magpro. Question I have is with its burning rate. Ive looked at many charts and some have it as fast as re19/4831 some have it right with 7828/re22 and some have it as slow as re25. Whats your experience with it and is it still a powder available from aa

figured it out. I don't have mag pro I have the older magnum rifle powder which is basically 3100
