You bet they have. Example:
I was on my high school rifle team, and I lettered in it. We stored the rifles at the school in lockers. We cleaned them there, and we trained with them there in non-shooting stance drills. We regularly carried rifles in and out of the school to our vehicles to go back and forth to the armory (where the range was) for practice.
Rifle team was very important to me when I was a high school student, and it was one of the interscholastic sports that I was *really* good at. We had an awesome rifle team, some members of which were olympic contenders.
My old high school no longer has a rifle team, for all of the lame PC reasons you might think.
Yeah, it's lame and getting lamer. I couldn't believe when I heard recently that there's a movement to ban competitive sports now because some consider them detrimental to children's self-esteem. (shaking head in disbelief)
