It's true that this is not a particularly inexpensive pasttie. The starup costs ar not as bad as being in the vintage car community, or IPSC or a lot of other hobbies but we understand it can be substantial. However I think we mus remain true to the original concept of the sport. Competetive shooting with Old West firearms. That's what drew most of us here. It was difficult for me to get geared up years ago. But I was determined. The "new category" suggestion comes up frequently from new shooters. Sometimes they want to use only one pistol, or no shot gun, or double actions or some other method to make it more affordable.
Many clubs offer 22 side matches at their bigger shoots. But to create another catregory besides what we already have would, in my opinion, be impractical for the reasons mentioned by other experienced members.
You wouldn't join a Harley club riding a Moped.
