Around 1982, I had Harry Creighton of Kingston Springs, TN rebarrel a Ruger #3 in .25/20 for me to use as a squirrel rifle. Topped with a Unertl small game 6x scope, it is the bee's knees for small game. I use mostly 69 gr. cast Lyman 257420's in it, but also used 60 to 75 gr jacketed bullets as well. Fun stuff.
