"Monkey metal?"" What exactly is the metallurgical composition in AISI numericals?? Most forged steel receivers, etc. are in the 4140 range- not certain about the "lodt wax" or "investment cast" metals Bill Ruger used. I am a welder by trade, and am always looking to learn more about metallurgy--Thanks- RWTF
