I grew up shooting competitively, from age 11, iirc. I fired many thousands of rounds of .22lr in smallbore rifle both indoor and outdoors, and some thousands of rounds of .308 in highpower rifle competition. later I did a little .22 pistol shooting. I shot in matches in 6 states, including the nationals twice, as well as one match in Australia, though it was a casual match. (Anzac day match outside Sydney. This was probably the most fun I ever had at a match. We performed a WWI style "walkdown" , and the only thing I have been involved in that was anything like it was the Military oriented "Infantry trophy" matches, also called "Rattle Battle" though they did not involve automatic fire. )
I have never known of an injury other than sunburn, heat exhaustion, or a rolled ankle from matches.
back in the late 70s and early 80s, shooters were almost like a family. THere were no serious fears about theft, though we often had well over a thousand dollars (then year) of equipment left at our firing points.
But then, school shootings were never discussed, afai remember, until the kid here in WA shot up his school.
