When I was in high school (1988-1992) my school had riflery for boys and girls. We shot .22 rimfire target/match rifles like the Remington 541x and Winchester 52D. Three position, 50 ft range. The range was actually on the school grounds. The coaches were the JROTC instructors for the school and the rifles were locked away in the JROTC arms room when not in use. There were only three other public schools on the island that had rifle teams so a season was competing against the other schools twice each, one away and one home match. Yes this was on Oahu in Hawaii. I was on the team all four years. However, years later they went to air rifles and demolished the range when they put in a new football field. I don't ever remember any controversy about a public school having firearms on campus while I was there, in spite of it being in Hawaii.
