When you’re kicked out of the service early in basic training you either have a physical problem that they didn’t catch at the physical or more likely, a mental defect of some kind. I know that all the trainees kicked out during my time in basic were fruitloops, not people with regular health problems. They missed me somehow. LOL
The Army must have changed. I was drafted in 1969. At the physical they asked me if I could hear the ligtning and see the thunder. I said what? They said “yer good to go.”
PS: I own an example of the Mossberg .22 shown on the BSA handbook; they built great target .22s and are probably still cheap to own.
