I own a Smith and Wesson Model 3 Russian which I assume is .44 Russian since I shoot .44 Russian out of it. However I had some .44 S&W around the house, lord knows where it came from, and they look identical and after a little research I find that other than the .44 S&W being externally lubricated and heeled vs The .44 Russian being internally lubricated there is no differences so is it possible to shoot .44 S&W out of the .44 Russian I know it sounds like a stupid question but just curious since the price difference between the 2 is substantial.
