If you meet any local people messing with the older stuff, you may find some people shooting for fun, but not doing the formal matches. Shooting old original Colts, Winchesters, Sharps and other classic stuff or repros of same has a lot of fans. I love the history and the guns, just havent gotten very interested in the way the CAS stuff is done. A few CAS shoots without going all in may be worthwhile just to meet people and mess with the guns some.
I stumbled on a group of mostly older guys out in the hills shooting rimfire in Az in the late 80s, I think they got together once a week, it was an informal thing out on National Forest land. I wouldnt be surprised if there were people meeting up shooting old guns. The net may be a way to connect. There were a few of us around Flag and Sedona years ago shooting old guns. It was just chance meeting people in gun shops, or over gun deals or friends of friends.
This somewhat reminds me of my motorcycle days. I didnt care to hang around with many of the people that seemed to be drawn to Harleys. I didnt drink, didnt like hanging out in bars, just loved old bikes and loved to ride. A few people of similar inclination hung together and we did a lot of great rides and camp trips. We had some good times at the Baskin Robbins also.
