Hello Folks,
My friend brought his 6" Model 14 to me. He said that for more than 30 years it has been the most accurate revolver he has owned. Then one day recently the accuracy went away. The sudden change made me think of a crack. I took the revolver home and examined it under bright light with high magnification, and could find none. He said the gun has only fired 148 gr and 158 gr cast bullets loaded to target velocity. The only thing I found was some lead buildup in the chambers. I thoroughly cleaned the gun and mounted a 2x pistol scope (it was already drilled and tapped). Using leather sandbags on a concrete bench, five shot groups were between 2-1/2" and 3-3/4" at 25 yards. My own Model 14 shoots around one inch. I reexamined the gun last night and can find nothing amiss.
What else should I look for?
Thanks, Tom
