Thanks for the info. My post-war Mausers all have nice tight bores, compared to my early(pre-war/wartime) Lugers. I have two(2) Bar-Sto custom barrels in 7.65Para, and the chambers and bores are minimal in diameter. I attempted to shoot some of the .310-.311in. lead bullets through these barrels, and had a real mess with heavy leading of the barrels. They get ONLY FMJ bullets of the correct diameter shot down them these days. I was fortunate to acquire a fair amount of the Swiss 92gr .309 FMJ bullets from GT, and they work great.
