I have a bit of Data from an old Lyman manual, but I can use use any experience or info on loading for and shooting these rounds. I currently have the Lee 312-100 (lapped to .314", weight approx 110 gr.) and TL314-93 SWC. This post is for a gunsmith friend who needs to cycle these guns for function test, primarily.

Both rounds used 87-93- grain bullets. Heavier bullet will intrude into powder space, increase loading density and run pressure up. Cast bullet diameter should be .309-.310, weight in your alloy should not be over 93 grains. I use Accurate 31-087T. Another correct bullet is Lee .311-93-1R at 1.125" OAL in the Luger and 1.28" OAL.in the Mauser.

4 to 4.5 grains of Bullseye in the .30 Luger, 4.5 to 5 grains max. in the .30 Mauser.
