I have been shooting at junk like old cookware, old appliances, etc for years and it's usually great fun.
I also see lots of videos and discussions about shooting frying pans and old cookware.
Mythbusters even have a video where they "bust" the boomerang bullet myth shooting at a frying pan.

Well, we accidentally proved the busted myth. My son was shooting at the frying pan with my Ruger standard .22 pistol at 25 yards.
I was standing a couple of feet to his left. His first shot missed. His second hit a little right and low of center and went through the pan. His third
shot hit the right side of the pan at the top of the curve, then I heard a whizzing sound and felt a sharp pain in the left side of my
gut. It felt like I was hit by someone swinging a fireplace poker full strength at my gut. I yelled "I'm hit!" and my son looked back at me in shock and disbelief. Fortunately I was wearing a thick cotton shirt over a T-shirt and while the bullet made a hell of an impression, it didn't penetrate my skin. Apparently it was tumbling, but was not malformed much because it made a neat profile impression of the bullet on my shirt and my skin.
So, if you're going to shoot at frying pans, my advice would be shoot at the back side, not the front!
And of course... pics! If you look closely you can see the path of the bullet acroos the pan.
