Enjoyed reading that. I have a CED Millennium chronograph (their first model), but haven't used it. Moved shortly after I bought it and the closest range doesn't allow their use. The other range just isn't close enough. I rely on book data and the target to develop loads. I did set the Millennium up once in the back yard just to function test it by throwing little foam golf balls through it. Didn't work at first. Had to throw them hard enough to exceed 50 fps and then it registered. It does have a 2 ft spacing though and optional 4, 6 and 8 ft mounting brackets can be used with it. Maybe one of these days I'll get to play with it. The tripod is an older aluminum one that belonged to my father. I'll keep that cautionary note in mind about the wind and add some weight for ballast.
