Yep, some brought .222 and 30-30 in their cars/trucks in high school to hunt after school.
We managed to not shoot each other. Somehow. I just don't know what changed. People didn't think anything about us kids having firearms and knives. We all had them. I had my first .22 rifle when I was 12, and a .22 semi auto pistol when 13. I was turned loose with the .357 revolver and high powered rifles and shotguns when I was 14. Kept the old Herters .357 revolver under my bed and the Arisaka Japanese 7.7 rifle and 16 gauge shotgun in the closet nearby. How many remember those old Herters revolvers? You could mail order them back in the 60s before the GCA of 68. They didn't cost much, about the cheapest high powered revolver you could buy. They came in .357 magnum .44 magnum and a proprietary to Herters cartridge called the .401 Powermag.
