RE: Mausers????
Before you start down the road of trail and error, take the rifle to your local gunsmith and have him correctly indentify exactly what round that Mauaser is chamber for. While he is at it he can check headspace, locking lugs, trigger, safety, and all the other important parts of function and safety. It will be money well spent, to ensure the 108 year old rifle is ready and safe to fire.
If my memory serves me correctlt, P. Mauser after designing the M-91 Mauser, began looking for military contracts for them. Spain was one of the very first takers of the M-91. As design modifications and improvements were added, the M-93, M-95, and M-96 models were created. For all practical purposes the M-93 and M-95 are the exact same gun. Of course the M-96, become more commanly known as the M-96 Swedish Mauser. Many od the countries using P. Mauser's design contracted with him to manufacture their own version.
The M-91 was chambered in the 7.65x54 Mauser round, later to become more commanly known as the 7.65mm Argentine round. The M-93 & M-95 were chambered in the famous 7x57 Mauser round. The M-96 is most known for it's chambering in the 6.5x55 Swedish round.
More than likely, what you have is an M-93 Argetine Mauser chambered in 7.65x54 or more commanly know as the 7.65 Argetine. The 7.65x54/7.65 Argetine case is slightly smaller in diameter at the base and shoulder by a few thousandths and .125" shorter overall length, than the 7x57 Mauser case.
Hope this helps. But I would still take it a gunsmith to confirm that the rifle is indeed chambered for the 7.65 Argetine round, and to see if the rifle is safe to fire.
