A chronograph really helps when loading for this cartridge. If you load a 22" barrel 7x57 with 154-160 grain bullets to between 2650 and 2700 fps using H4350, you will be getting pretty much everything out of the round that it is safely capable of. And it will kill well and not beat you up. I don't mention a powder charge weight because throat length, and thus pressure and velocity with a given powder charge, vary enormously with this cartridge depending on who made the rifle and when.
