I would say that any load that would be dangerous in the Mauser, would also be dangerous in about anything else, including the Ruger.
Perhaps. Spanish Mausers are tough, but they were originally designed around a cartridge that generates about 50K psi. Rugers are routinely chambered for cartridges that generate 65K+ psi with never any talk about locking lug setback or growing headspace. A am a big fan of Spanish Mausers, owned and shot several of them for about 10 years, but I also realize they have their limitations.
