Oh, the humanity! Here is why you should never, ever put ammunition in the microwave.
These days .22 ammunition is hard to find and costly. What happens, though, if they get microwaved?
This experiment has been done before, but what kind of different results happen with .22 long rifle ammunition? Some of the cartridges do pop open like fireworks but only the bullets and casings separate. It takes a gun barrel to direct pressure to create a real bullet power projectile.
Save your microwave and your precious boxes of hard-earned .22 ammunition.
Do not try this at home but instead leave it to the guys in this video to see the results of this experiment.
