Congratulations on shooting a classic cartridge. I like the 7x57 round.
Some reloading manuals have data specific for both older and newer rifles in 7X57. The manuals will give advice on which loads can be used in different rifles. I would consult the manuals and abide by the information in them. I have used a number of the newer loads in a Ruger 1-A. Those loads perform similar to a 7mm-08.
