Went to the range (indoor) last week with the .44 revolver.
With 23gn fffg loaded, you pull the trigger and the world ends in a deafening roar, a blinding flash and a cloud of smoke.

I fired several shots with no trouble and had just squeezed the trigger to send the fourth on its way when all the lights went out. All I could think of was "####, what the hell have I hit".

The timing couldn't have been better and I thought I'd drilled through some wiring somewhere.

It was a power cut though (phew).
