Need help...30 Luger Reload recipes

unspellable · 06-04-2004, 02:51 PM

Bullseye and W231 are probably a bit too fast for max loads. The 7.65 mm likes its powder a tad slower then the 9 mm. Unique should do well.

The original nominal groove diameter of 0.311 was over sized. The problem with using bullets sized to groove diameter is that you may run out of clearance around the case neck. If the neck does not have room to expand prssures will rise...

This may or may not be a problem, but it's something to watch out for. There are a few rebarreled Lugers around sporting barrels made from US manufactured 30 caliber rifle barrels, in which case the groove diameter will be 0.308.

Quick and dirty test:

Take the pistol apart and hold the receiver/barrel assembly muzzle down. Drop a loaded cartridge in. It should fully chamber of its own weight. Turn it over and it should fall out of its own weight.
