I have recently made a 40mm steel cannon. it is 4 feet long and weights 35lbs without the carage. I use 100grams of blackpowder as a propellant and a steel 35mm by 35mm cylinder with a cotton sobot. the main barrel is made from 1/4" DOM (drawn over mandrel) tubing that has a psi rating of 45,000psi.
has anyone ever made and tested their own cannon, howitzer, or mortar? if so...give some specs about it and your results.
I didn't find the right solution from the internet.
