I have a question for the S&W N-frame collectors and historians on the forum. Did the Smith & Wesson factory make a habit converting Outdoorsman revolvers to 1950 Targets during the 1970's? I purchased this revolver 2006. It came with the factory letter and the six-inch barrel installed. The four-inch barrel packed separately. I shot with the six-inch for a couple of weeks and then installed the four-inch as I already had a six-inch Model 24. Both barrels produced 3-inch groups at 25 yards with a 1000FPS load of 2400 and the .432 250 gr. Keith Bullet. The Forcing cone to cylinder gap with both barrels are .005 relaxed to .007 snug. Serial numbers match on both barrels and the frame. In the attached Factory Letter, Mr. Jinks Provides a through history of the Heavy Duty and Outdoorsman. The last sentence of page 2 begs the question, was this a standard practice? Any input would be appreciated.
