I have an IMR manual from 1972 and ones from 1982, 1994 1999, and a lifetime supply of 4756. It's interesting reading over my reloading notes when I was in my early 20's. The interesting thing is even back then I was concerned about low pressure (then it was LUP) and velocities at or around 1200fps.
