Due to age and injuries, my shoulders do not hold up full size handguns well anymore.
I checked with a Cowboy Shooting club to see if they had a .22lr class where I could compete using my Ruger Single Six thinking that would be fun. Answer: No. They do allow children to compete using .22s but nothing for adults. I was dissapointed and expressed the opinion they were losing out on possibly losing new shooters by not offering entry level matches in the rimfire division. Not everyone owns a .45lc single action but they might work up to it if the sport interests them. But, that's my opinion. They don't agree.
