All these newcomers! I got my first ML in 1960, when I was 15. Got to getting into mischief, so Dad introduced me to a friend of his that was a History prof at U Maryland. He was a big Civil War buff, and had formed a shooting team for the reenactors and target shooters.
For a $20 bill, I became the proud owner of an 1861 .58 cal Springfield musket. We were in the Washington DC area, and travelled around to about all the military bases in the area, shooting at the 100-yard targets. These were mainly 24 clay pigeons taped to a 4 x 8 sheet of plywood - first 8-man team to bust all their targets were winners!
From time to time we did have other targets - the one I recall most was a 1/4 stick of dynamite with a blasting cap on top. That one was individual shooting, and I cannot recall me ever being the one to hit the target.
We all wore period clothing, most were original, 100-year old stuff.
Alas, Dad got out of the Navy, and took a job down in Florida, where there seemed to be NO ML guys at all. Then, of course, I went into the Navy as well, and Vietnam started while I was in boot at San Diego.
