Yep, We shoot "buffalo" matches at a local club and we barely have enough "old" folks to make it worth the effort to have a match. Cowboy is way down and will die when my generation is gone. 1000 yard benchrest is way down from what it was when I shot it regularly a couple decades ago. The action pistol matches in the area draw lots of folks. The younger generations are drawn to that and it is easier/less expensive than some other shooting sports.
10 years ago, when I was in my mid 50's, I went to my excellent range to check out a black powder silhouette shoot. All were using Sharps type rifles from 100yd out to the 500 yd rams. I was fascinated and after the shoot, two of the 70-80 yr old organizer members set me up to shoot one of their rifles. I was amazed that I was able to hit the 500 rams once I got used to the set hair triggers. By the time I was done I had offers to purchase a rifle at giveaway price and join up. There were about 10 guys at the shoot and when done, everyone just split because they had 'stuff to do' and left these these two old guys to do clean up, gather up and store all the heavy steel targets, and there were alot of them! Of course I helped but the lack of camaraderie turned me off.
I also thought about joining the local F Class gang which used the Camp White range. I knew one of the shooters and he invited me down to observe a practice, It was the same thing, a dozen guys showed up, some late, shot and then after the shoot nearly all of them chatted for a minute and then split, acting like they were on a lunch break. And they would only practice shoot like this once a month.
I dunno I guess being a 'rifleman' is a dying breed! I was hoping this would be a good chance for me, an outsider, to meet up with some guys with common interest and possibly make a few friends. But not, most seemed to be too chained to their lives to take some time out. It was a Saturday too in both instances. So now I just go out to my ranges in the mountains close to my home and do my own thing. Maybe it is different back in midwest and east.
