Hmmm.... did you notice the huge fireball in the slow-motion shot? I'm not ready to blame Taurus for this one.
Yup. My thought was. The barrel is plugged. Gasses have to go somewhere.
I get that way a lot too, but a spoonful of Metamucil and it all goes away!
Regarding the "Huge fireball". Take a look at these stills from a video of an HK45 firing Remmington 230gr .45 JHPs
The fact the flash is not coming, primarily, out the front of the barrel leads me to believe there was a blockage.
