Hi there, just curious if anyone knows about or has experience with the model 93 mausers, specifically the ones produced at the Oviedo factory in Spain. I have heard that there were some questionable metalurgical practices that went on and that these rifles are unsafe to shoot. Is this true, and will the model 93 (small ring) handle modern factory loads if the headspace etc. checks out?
Thanks in advance
 
The '93 mausers are alright, just reload within the parameters of 45,000cup. A '93 using 7x57 will perform fine and give years of safe service. They will not handle modern factory loads designed for newer rifles or the '98 mauser action. The problems came when they rebarreled some of the '93's to chamber a higher pressure .308 round (7.62 cetme) as a transition to firearms that were built for and to accept the 7.62nato round. Constant use of this round will cause lug setback, and a '93 mauser doesn't have great gas deflection should the case or primer rupture. If you have a '93 chambered to 7.62 use reload data for the 300 Savage. The other problem came with commercial '98 mausers (Santa Barbara) produced at Oviedo, was with the heat treating which was done by "eyeball" rather than time and temperature, so these actions are regarded as soft and prone to setback.
 
I have a 93 Spanish carbine in 7x57. It loves the 175 grn roundnose bullet at about 2300 fps. I use 44.5 grains of H4831, which is a mild mid range load, slightly under 40,000 psi. Shot a deer with this rifle and load at a measured 175 yds, the bullet passed right through for one of those blessed almost instant kills. Very little meat damage and alxo a very accurate combination. I will admit, it wasn't an off hand standing shot, but it was with an unaltered 93 full length carbine. If your rifle is in decent condition, all of the earlier mausers as well as every other rifle made at that time were heat treated by the eyeball system, and a very good job those early craftsmen did. bearhunter
