This analysis from Mark Serbu, owner and lead designer of Serbu Firearms, details the catastrophic failure of the RN-50. The primary cause identified is the use of fast-burning pistol powder instead of the appropriate slow-burning .50 BMG rifle powder. Serbu uses ballistics software to illustrate how incorrect powder choice leads to extreme pressure spikes far exceeding safe limits, emphasizing the difference between failsafe design and absolute fail-proof protection against misuse.
