If you're shooting at a centerfire pop-up, or rotating target with a .22, yes, you may experience ricochets. They are meant to be moved by much higher energies. But if you are using a .22 movable target you should have no concerns at all. They are designed to give-way with the expected .22 caliber energies, so your bullet path is not affected dramatically.
Steel targets tend to have minimum distances for safe use in the fine print. AR500 steel is preferred over softer steel if you wish them to last very long. And you do need to get the .22 targets rather than the ones designed for larger calibers. I'd get one from Midway or Brownells or one of the target mfgrs. If you are having trouble locating .22 (or any other ammo) you may wish to keep an eye on slickguns.com.
Thanks for the link to slickguns.com. I checked their site and all their 22LR Ammo is marked Out Of Stock. I bookmarked them to my "Favorites" and will keep checking them.
Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
You can tag items there so that you get an email notification when they are posted again. In the past year, many of the deals posted have sold out in minutes, so you either have to tag them or keep checking the site multiple times a day. But I have used that site to purchase thousands of rounds of ammo at great prices in that time frame.
