"I own a Mannlicher-Schoanauer model 1903 carbine which uses an almost identical round. I have not slugged the barrel but it is factory marked as being 6.7mm which is a diameter of .2637". This is the bore diameter, not the grove diameter. As has been correctly pointed out, all current and past 6.5mm bullets, with the exception of the Carcano ones measure .264". Steyr, the maker of my rifle, knew this yet still produced rifles with a a bore diameter of only .003" smaller. I would guess that grove diameter of my rifle is at least .268. The author of the document linked to here has identified one rifle with a groove diameter of .269"! Remember, all the available ammo used .264" bullets."
I suggest you find yourself a better coach.
I hate to keep contradicting you but, 6.7 mm (.2637") is the GROOVE diameter of a 6.5mm Mannlicher-Schoenauer rifle, not the BORE diameter. The bore diameter of a 6.5mm M-S, plus a 6.5mm Carcano, plus any other 6.5mm rifle you care to discuss is, as any fool can figure out for himself, 6.5 mm or .256"!!!
The 6.5mm Carcano has a GROOVE diameter of 6.8 mm (.268"). Despite what you have tried to tell this forum, Italian Carcano ammo bullets measure .268". If it was acceptable to shoot .264" bullets from a Carcano, why did the Italians go to all the trouble of making the unique .268" bullet?

Mr. HILL. The right rear portion of his head was missing. It was lying in the rear seat of the car. His brain was exposed. There was blood and bits of brain all over the entire rear portion of the car. Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not, except for the one large gaping wound in the right rear portion of the head.
