RN 50 Blow Up...CONCLUSION!

Published on September 13, 2022
Duration: 14:52

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.

Quick Summary

The RN-50 firearm failure was caused by using fast-burning pistol powder in a .50 BMG rifle cartridge. This incorrect powder choice led to extreme pressure spikes far exceeding safe limits, demonstrating that firearms, while failsafe, cannot be made fail-proof against severe misuse.

Frequently Asked Questions

What was the primary cause of the RN-50 firearm failure?

The primary cause was the incorrect loading of ammunition. Fast-burning pistol powder was used in a .50 BMG rifle cartridge case instead of the appropriate slow-burning rifle powder, leading to extreme and catastrophic pressure spikes.

How does powder burn rate affect firearm pressure?

The burn rate determines how quickly a powder releases its energy. Fast-burning powders release energy too rapidly for a rifle barrel to safely contain, causing extreme pressure spikes. Slow-burning rifle powders release energy over a longer period, keeping pressures within safe limits.

Can a firearm be made completely 'fail-proof'?

No, firearms cannot be made completely 'fail-proof' against extreme misuse. While they can be designed to be 'failsafe,' they cannot withstand intentionally or accidentally created conditions like excessively high pressures resulting from incorrect ammunition loading.

What is the typical safe pressure for a .50 BMG round?

A standard .50 BMG load using appropriate rifle powder typically operates at a peak pressure of around 55,000 PSI. Incorrect powder choices can generate pressures exceeding 400,000 PSI.
