I've loaded and shot 100s of 7.65 Luger cartridges with Hornady's .312 XTP 100 and 85 grain. They are and were extremely accurate in all of the 7.65mm Lugers I've owned. No pressure or fowling problems at all. These bullets were designed for the Win. 32-20, which I have also loaded many rounds for. I've slugged both rifle and revolver 32-20 barrels that measured from .309 to .313 and they functioned well in all of them. I also use them in 2 Ruger .32 H&R Mags with a .309, and.310 bore dia.
