Destry,
I remember 3oz shot but don't remember the amount of powder, remember that it was full of 2F. The film is of my friend Mike who, in all fairness, was standing on some very slipper ice ;-). When I shot the gun there was not a step backwards but then I'm a little larger than Mike.

Mark,
I was laughing so hard that I forgot I was running the camera and pointed it at the ground, a fun day.
