reloading my 9mm 1939 Mauser luger with lead bulets

[Sieger]

Hi:

If you search my name, you will find several outstanding loads for the Luger, both in FMJ and lead. When I say outstanding, I mean 6 or 7 to one hole at 25 yards (over a sand bag).

Your powder is a bit too fast for best accuracy and function in a Luger. My best lead bullet powder, to date, has been AA#5 (Accurate #5). With this powder and 124 gr. RCBS TC bullets, I can shoot 6 or 7 to one hole all day long. Here is the load.

RCBS 124 gr., TC sized to .356. Over all length (critical) is 29mm.
WWC surplus cases, standard small pistol primers.
5.4 grs. of AA#5.

Again, Lugers "prefer" medium burn powders, why, I really don't know or even care, as I have learned never to argue with success.

Regarding over all length, I also have a thread on setting this up properly for the particular bullet you are using. With a Luger, over all length of the cartridge is critical to proper, jam free, operation.

Good luck and feel free to PM me with questions.
