6.5x58mm Portuguese Vergueiro

6.5x58mm Portuguese Vergueiro
Warning! Notes: Historical Notes: This was the original Portuguese military cartridge for the Mauser-Vergueiro bolt-action rifle - a basic Mauer-type, but with certain Mannlicher features such as the split-bridge receiver. In 1937, Portugal adopted the 8mm Mauser cartridge and the Model 98 Mauser rifle. Many of the older Vergueiro rifles were then rebarreled to the new round. Mauser bolt-action rifles have been chambered for this round in England and Europe, but it has never been used by any American manufacturer. General comments: The cartridge case is similar to the 6.5x57mm Mauser in shape and performance, but is a little smaller in diameter, with a longer neck. It is a good hunting cartridge for North American big game and ranks along with the other military 6.5s. Since the old Vergueiro rifles were largely rebarreled to 8mm, only a relatively few of these in the 6.5mm appeared in the surplus military gun stores. No commercial manufacturers currently offer this ammunition. (Cartridges of the World 12th Edition)
