I have reprint and original Lymans' manuals going back to 1953 I use to cross-reference powder and bullet combinations when working up a starting load. It's a method that generally works for me but some of the data I know is based on the observations of the authors and editors, not hard data. I also know a lot of the pre-'74 data is going to be based on hard data collected by not-very-accurate testing equipment. I take these things into account and work up what looks to be the surviving combination from decades of experimentation. I'm curious to know how far back other experienced hand-loaders go when researching a new load. What's your oldest manual and how old is too old for a published load to be still worth considering?
