A: The Ruger Vaquero is well known for being a tough and durable firearm, capable of handling loads that are more powerful than standard .45 Colt ammunition. To determine what your exact weapon would be capable of, it would be best to contact Ruger and give them the serial number, then ask about pressure limitations. Also, make sure that it is not a New Vaquero, as the two are capable of handling different loads. In addition, there might have been manufacturing changes over the years that increased the strength of the weapon. In any case, this Fiocchi .45 Colt ammunition is not loaded to higher pressures and is safe to fire in any modern production revolver that is marked by the manufacturer as being intended to fire .45 Colt.
