You mean shells? He may not have had any. I work with an old guy who set out to make his own "shotgun" when he was 9. He took a piece of plumbing pipe with an end cap, drilled two holes near the end for the electrodes (pencil lead), and then packed it with a few hundred match heads and some BB's. He ran wire from the electrodes to his safety spot behind a berm, and touched it off with a battery. It blew apart his target, and he said the smoke could be smelled across the entire farm. If a 9 year old could figure it out in the 1950's, I'm sure an adult, hell bent on murder, could figure it out today.
