Sorry for this delayed response post. I have not been feeling well for some time but still enjoy reading the posts here. The original intent was to seek the most popular FIELD artillery gun, not the heavier or lighter artillery pieces. My choice continues to be the 12 pounder Napoleon, a field weapon of flexibility, durability, having almost no burst barrels during the civil war. The gunners thought it safe to fire. Meanwhile, the 3" Ordnance rifle had few burst barrels and were thought as a safe gun for the crew to fire. The 12 pound James Rifle was an interesting artillery piece as it had a rifled barrel made of cast iron was a metal that was a soft metal and the rifling wore out with us. Both the just mentioned James Rifle and the 3" Ordnance Rifle did good service but suffered from use.
(nice to be back)
Keep the guns moving.
