It's actually in a Winchester 1885 High Wall. Action from 1904, CP Donnelly barrel, English Walnut stocks by Russ Wilson. Scope Unertl Ultra Varmint 12x. The 22/39-30 AI does fit in between the 22/250 and the 220 Swift. 55 gr bullets at 3800 fps. I did an article on it several years ago for Handloader Magazine.
