In my older Lugers I've often shot .312" bullets weighing from 85 - 90 grains. With Winchester brass, your chamber may accept a cartridge loaded with .312" bullets without a problem. On Remington and Norma brass - as well as reformed 5.56mm cases - I've had to reduce neck thickness to .008" in order to load .312" bullets to fit my chambers.

Thor, you may want to try Hornady's 85 grain XTP HP bullets. It works well in my older Lugers. It has a crimping groove (cannelure) which helps. Try 7.5 - 8.0 grains of AA #7 powder.
