Thanks on the cannon. I made it when I was 25 years old and yep it shoots. A blank charge of 1000 gr. FFF makes her buck and roar.
Joel, here's your "farm implement grade"
American made scratch built cannon picture that you wanted posted........

Amarillo could harness his dogs up to this gun carriage and tow this old girl around while shooting his midget quail with about 5 lbs of number 7 lead and get a few at a time.......

.....then he would only have to carry "dog food and water" in saddle bags on the gun carriage with his shot and powder......with rubber tires on it she'd go right over cactus and mesquite stubble......
