Thanks for re-kindling this thread, Dan. I had a Stevens 44 in .22LR drop into my lap with a worn out bore that'll be lined with a new .22RF liner. Was thinking in terms of cutting a .22LR chamber and calling it a day, but by simply fitting a CF breech block in addition to the current one I can make it a dual purpose lead spitter. Other momentous life interruptions had shoved the .22 GTC onto the back burner but you reawakened the idea. Darn you!
