I have a pound of the old style unique and don't have any data for it. can anyone help? I reload for .45 acp, .40 S&W, 9mm Luger and .357 I would just like to use this stuff up. How I got ahold of this is a whole other story. I bought this from a gun store about 4 months ago (with no data) when I found out there was a difference between the old and the new I tried to return it and they wouldn't take it back. OK, live and learn. Am I right in assuming I cant load the old stuff with today's data?
