I've only IDed a few finds, but seems the more I read, the more it opens my eyes up to the sophistication that was around during those times. I spent a number of years in artillery as a Forward Observer and Cannon Crewmember and specifically handling ammunition and it amazes me how a lot of the same technology that we use today had some rudimentary form of it 150 years ago.
Specifically, they say that 80% of the causalities are caused by artillery and it was hard for me to believe until I experienced it first hand or handle and see rounds such as grapeshot. I remembered learning artillery and it was surreal to realize that I had the potential to kill people from miles away with a piece of steel that I was carrying in my hands. While I was on active duty we fired a number of 105mm rounds into a forest for 5 minutes as quick as we could (approximately 5 rounds a gun with timed fuses) and we completely leveled the forest. Reminded me of the 80's movie called the "Predator" where they have the "mad minute" with their machine guns. 100+ year old trees were splintered to pieces. Bad news to try and take a artillery battery with a frontal assault.
To sum up this long winded message, it amazes me that people are evil when it comes to ways of designing things to maim or kill and in reading and studying and seeing different, old projectiles, the war making business has been the same for centuries.
