Shawn:
Frankly, I could see no point whatsoever in a "little" Sharps. It was the second silliest idea I ever heard of. Then I met one at the Silhouette Nationals a couple three years ago and fell in love with it. As I recall it was in .22rf but I don't remember who made it.
I cannot speak to the quality of the one you are considering,as I don't know it is the same, but the one I held would be a treat to shoot in one of the chambering you are looking at. It was a wonderful little rifle.
Best of luck to you.
