I too have dreamed of a reloadable equivalent to a 22lr. I still have dreams about a Ruger Mark II in 25 or 32 acp. What a bunny/squirrel gun that would be. I think the 32ACP might be a better choice though. Easier to load(especially for us fat-fingered folks), easier to cast for, and larger diameter.
I guess one of us is just going to have to get in touch with a custom barrel maker ans have one made. Unfortunately, I'm broke, so you'll have to step up to the plate :grin: .
