Is the Serbu RN-50 Safe? Mark Serbu Interview
This interview with Mark Serbu addresses the safety of the RN-50 firearm, particularly in light of an incident involving Scott from Kentucky Ballistics. The consensus points to a misloaded cartridge, likely using pistol powder in a 50 BMG case, leading to extreme over-pressurization (estimated at 190,000 PSI). Serbu explains that 50 BMG's normal pressure is around 55,000 PSI and discusses the difference in energy release between various propellants and explosives, emphasizing that impact loading from rapid-burn powders can be destructive.
