Dear fishonabike: The old time carnvals I mentioned used twenty-tw9 short cartridges in
a pumpgun. I never saw an automatic rifle in one. That would have made ti too easy.
And the range was about twenty feet. The challenge was to aim, fire, and pump in a
new cartridge and aim again fast enough to be able to fire about every two seconds before
the moving targets went over edge of table, down under the table and back to starting
point. I never saw an air rifle that could fire rapidly enough to use against those rather
heavy metal targets to take advantage of "having your ducks in a row".
Incidentally, the rifles were on a short chain to prevent accidents.
