I have been reloading both 6.5 and 7.35 Carcanos for many years. Always used .268 and .298 bullets respectively and get great performance out of these old rifles.
Last range trip, and for the first time I decided to try some 6.5 Prvi Partisan 139gr FMJBT factory ammo though my 91. At 50 yards using a rest, I fired an 8 inch group. I switched to my reloads and fired a 1.5 inch group.
After the range trip, I pulled the bullet from the factory round and it miked exactly .264. Problem solved.
I know someone will say their rifle will shoot good with 264 bullets and I agree, some will. The original rifle was designed to shoot .268 diameter bullets.
