Our Assessment: This is a beautiful custom “double square bridge” Mauser made at the Mauser weapons factory in Oberndorf, Germany. It has an octagonal barrel with a hand engraved top rail, finely checkered square bridges, and a tangent sight that is marked out to 1000 yds. The metal still has most of its deep blue finish which looks great set in the custom hand checkered stock. The bore is still strong and bright. This is an ideal rifle for the Mauser collector.
The rifle is chambered in 9.3x62mm. Here is an excerpt from the article “Greatest Cartridges: 9.3×62 Mauser, Effective on About Everything” from Gun Digest at http://www.gundigest.com/ammunition-reviews-articles/greatest-cartridges/greatest-cartridges-9-3×62-mauser-effective-on-about-everything: “The German colonists living in German SW Africa and German East Africa were very active in complaining to the home country for their need for affordable rifles and ammunition suitable for use against Africa’s big and dangerous game animals. Germany was already producing what was to become the best bolt-action rifle available with their Mauser Model 98. They just didn’t have a powerful enough cartridge to fit in a standard Model 98 length, to do battle against Africa’s dangerous fauna. Early in the twentieth century, a gunsmith by the name of Otto Bock, took on the task of developing such a cartridge. In 1905, he introduced the results of his developmental efforts, the 9.3×62mm cartridge – also known as the 9.3×62 Mauser. The cartridge featured a 9.3mm bullet diameter (.366”) loaded into a 62mm long rimless case. The cartridge was originally loaded with a 285-grain bullet with a muzzle velocity of 2150 fps. It fit nicely in a Mauser 98 action, and operation and feeding was excellent. Later, the cartridge was juiced up a bit, and loaded primarily with a 286-grain bullet with a muzzle velocity of around 2400 fps. The CIP established a Maximum Average Pressure of 56,500 psi. In modern strong rifles, there is no reason that it could not be safely loaded to 60,000 psi, providing around 2500 fps, if such was deemed desirable. The cartridge became exceeding popular in Europe and in Africa, and still is today.”
