In my youth we brought our .22 rifles to school on Mondays because we used the range in the school basement for target practice (under adult supervision of course). Try that today and get swarmed by the local SWAT team.

PS In high school shop class I refinished the stock on my .22 auto loader.
We never took weapons into school, but during dove season those of us old enough to drive had a shotgun, or three (ours and two friends) in our truck, and in the dead of winter we had a .22 for running trap lines before and after school.
