I'll be very interested to hear how it turns out. Always has been an article of faith with me and all the shooters in my old bullseye league that 22's should never, ever be dry-fired. As you undoubtedly know, fancy European target pistols come with various dry firing devices to keep the firing pin from peening the chamber after the extensive dry-firing that serious competitive shooters usually do. Still, I will admit that I've never empirically tested the effects of much dry-firing with a rimfire, so I'll be, as I said, most interested to hear the results. In the meantime, I think I won't dry-fire my 22's except with an empty (frequently changed) in the chamber.
