In the mid 80’s I worked on a project where the uUSA bought bullet painting machines from France, I had to rewire them and program the Texas Instruments PLC that the Army specified , then we had to run 100,000 rounds of dummy 5.56 through the machine three times to show reliability. Then we had to prove we had the 100,000 dummy rounds and that none were in the machine. The machine painted the tips to show what type of round was being processed, and then this feed into the feeder machine for a belt linking machine, This was about time the saw was being introduced. It was then shipped to Salt Lake City. Must have worked, never heard anything about it after that.
Good story, but I can’t say that I can fully follow it!
