In a pawn shop recently and took a look at a sporterized military rifle. I did not recognize what it was but was impressed with blueing and finish on receiver and barrel. What few visible stamp marks that were on metal, revealed nothing about its origin. Owner of pawn shop did not know what it was. However, clearly stamped on receiver, above chamber, was .257 Cal. At home went to a web site and ID'd the rifle as a long barreled Italian Carcano rifle, which is a 6.5mm. Curious I thought, why .257 stamped on receiver? Also, Carcano in pawn shop had no box magazine that protruded from bottom of stock. Someone had converted external magazine to a stacked magazine in stock.
So anyone out there aware of importers stamping .257 Cal Carcanos or should I assume it has been rechambered to .257 (Roberts?). I own a .257 Roberts and will take one of its rounds to shop to try in Carcano.
