One of the sweetest shooting rifles that I have ever fired was a Winchester Model 92 in .25-20 that my brother owns. It had an action so smooth that it worked like teflon on teflon. The Model 92 is, of course, the version of the Winchester that you usually see in all of the old western movies, such as the John Wayne films, and it was the basis for the rifle in "The Rifleman" tv series with Chuck Connors. They had placed a flip-out tab on the trigger guard so that he could do the rapid fire trick with it. I know of a few teenagers from tghe late 1950s who jammed the triggers on lever action rifles through their fingers trying to duplicate that trick w/o the flip-out tab. The Puma Brazilian rifles use the Model 92 design, but their actions are nowhere near as smooth as my brother's rifle.
Another weapon of his that was awfully nice was a .41 Colt Single Action Army with the Bisby style grips on it. Very accurate and very easy shooting.
