Not desgined to shoot the 22 WMR
Magnums usually shoot faster. Hence the term Magnum
Needs to be examined by a good gunsmith
If the barrel says"2 3/4 inch shells", don't shoot 3 inch magnums. You might get away with it for several hundred shells, or you may crack the stock or forearm with the next shell you fire. If you want a magnum, go buy one, and save the Auto 5 for pheasants quail, and rabbits.
Yes they did. I have one. It is a jap made light 12 but they did make one. It is a quail killer. Perfect for the woods and a joy to shoot.
