The Carcano cartridge is 6.5x52 (rimless) and has a larger head diameter than the 25-35/ 6.5x52R (. 442"vs .422"). It is known that permitted pressure for the 6.5x52R is significantly less than for 25-35, but the American ammo has been used in 6.5x52R "Bring Backs" since the end of the war and the only complaints I have heard about had to do with different points of impact. Bullet diameter for the 6.5x48R S&S, 6.5x58R S&S, and 6.5x70R is about .261"; but 6.5x52R is very close to the .257" of the 25-35. Even in this small Alabama town I was able to buy 24 ga. shells through the local Feed & Seed Store. There is no directory of workmen's touchmarks, so initials found on German guns are difficult or impossible to ID, whereas trademarks may be identified.
