As it was, when I experienced a "M" split with the round in the chamber, I only got a dose of gas and brass in the face.
You mean the blowup squeezed brass past the closed bolt? That's a new one on me. I can only guess that the brass bits were channeled between the bolt and the receiver where sufficient pressure can build up to launch the bits backwards at high speed. One thing that can be said for the SMLE design is that the base of the case is so near open air that when something lets go the pressure is released almost straight away.
All the same, a great reminder as to why we must always wear our safety glasses.
