No. Not only more powerful and longer, they are larger in diameter, and will not fit.

yes.The Winchester model 9422M was chambered in .22WMR.
Your Winchester model 9422M,.22WMR caliber was made by Winchester in 1974.
The Winchester Magnum Rimfire is a larger round, and is capable of producing twice as much energy as the .22lr. I do believe that Ruger is making a rifle capable of handling the .22WMR, but a standard .22lr rifle is incapable of safely firing the .22WMR.
With the seial number that you provided,your Winchester model 9422M .22WMR was made in the year 1991.
