In the 1930s my mother was a young farm girl. Her father had passed away and her brother gave her a 1923 Commercial Model .30 Luger for protection after he left the farm for the glamor of being a Hollywood movie stunt man. She slept with it under her pillow until she married my dad just before WW2. I remember it was very accurate with Winchester Super X. Remington wouldn't even cycle the action. I still have 200 rds of Remington and if I ever find who has the Luger and can get it back I'll certainly try handloading your recipe(I've got some .30 dies) I'm thinking a Hornady's cam lock bullet puller might be the best tool for the job of salvaging the Remington brass and bullets.
