I agree that the Lymna manuals contain a lot of useful info. The reason for this is they have no bullets or powders to sell, so they are pretty broad-minded when it comes to loading data. Yes, you can use the RCBS dies with almost all other brands of presses. If you can get that Lyman Handbook No. 39 for a low price, buy it!! It is a classic, and contains some info no longer available anywhere else, even if the majority of the loading data per se is pretty much outdated. I have a copy of No. 39, and enjoy reading parts of it still!!
