Many years ago I purchased a Mauser "Broomhandle" in .30 Mauser, and reloaded converted .223 brass with a set of .30 Mauser dies and some reaming. I also bought a CZ 52 in 7.62x25 and always wondered if cases for this round could also be reloaded with the same .30 Mauser dies (RCBS). From a recent thread discussing these two rounds I have been considering purchasing the proper Starline brass and getting back into shooting these two firearms, knowing that they take different pressure loads to operate correctly.
