Cast bullets for Mauser Parabellum

RAY1946:

Here are some answers to a few of your questions above.

Groove diameters are very standard on Lugers. My 1917 DWM and 1941 Mauser are both in spec. at 9.1mm or .358 inches.

Because I have "vintage year" Lugers, the chambers are stepped. When you look at a fired casing, you will see this little step. This was designed into the chamber to aid in sealing the case to the chamber wall upon firing.

I bought 10,000 of the RCBS 124 gr TC at an estate sale (back in the day) on ebay. They were dirt cheap and were a real quality casting out of what appears to be linotype. The diameter is at .356 and they are lubed with the standard NRA formula of 50/50 beeswax and alox. The key to an accurate bullet with these (as well as most cast bullets) are square and true bases.

Please let me know how you are progressing.
