.30 Luger vs. .30 Mauser

I'm under the impression that .30 Luger and .30 Mauser are different rounds, with different lengths, cases, and charges. Is this so? If it is, can anyone give me a metric measurement for each? Also: Is the .30 Mauser round the same one the soviet block used in their pistols like the CZ-52 and tokarev?


I'm trying to find out how hard it'll be to get ammo for a Broomhandle Mauser, and what I can substitute for .30 Mauser if I need to. Any help is appreciated. Thanks!
