I use 5-5.2 grains of Unique. With the 100 GR Hornady XTP HP .312 bullet. It's made for 32-20. Start off at 4.5 GR and work up. The pressures are higher because of the tighter fit of the bullet. Guns cycled perfectly. Check for pressure signs as you do so. Slug your bore and get an accurate diameter. If it's .310 or above? You'er fine. If it's less. Use another bullet. I've used this load in a .309 bore, without any problem. I don't advise that anyone else does. It's your decision.

As the grooves are oversized (.311 grooves vs. .308 projective), I have also been interested in using larger bullets (in lead anyway) in the 7.65.

In your Luger's chamber, is the case a tight fit with the .312s you are using? Should I have any concerns here?
