The case rim on the WMR is also thicker then the rim of the LR. It will eventually detonate...
What will detonate? Why would it?
You hear questions like this every so often, but usually it's someone asking if you can put .22 short in a gun chambered for .22lr. The answer is yes, it will chamber, but no you shouldn't pull that trigger. The best outcome in such a scenario is nasty fouling in the chamber of your gun, possibly preventing future rounds from seating correctly, and the worst outcome...well, I'm sure someone out there would miss you if you departed this world.

As already mentioned, rifles have been made by many manufacturers that are designed to shoot 22short, 22long, and 22lr. Mossberg have made them since the 1920's, in single shot, tube fed, and mag fed versions. There are even some semi's that can handle both short and lr...
So why do you suppose that many rifles were stamped 22short,long,long rifle by the manufacturers? It's perfectly safe to use 22shorts or 22longs in a 22lr chamber.
