Video - Springfield Trapdoor backfire

I thought this should get more attention from Trapdoor owners out there, like me, who reload.  You can see the breachblock fly open and the spent casing jump out.  Not quite as catastrophic as a real 'kaboom,' but I always imagined the shell would go flying backwards like a rocket in such a scenario.  Since the video poster didn't respond to comments I can only guess that he was shooting smokeless rounds reloaded hot.


...And starting now I'll never shoot smokeless through my Trapdoor again!
