I grew up the same way and looking back I realize that most of the "steel" we had available as "targets" would have been scrap crap like old brake drums, junk cars or other trash that would be a ricochet or bounce back hazard. Today, with the wide availability of AR500 steel plate, we can safely shoot at these flat, hard surfaces that will cause a lead or cup and core bullet to completely disintegrate upon impact. That said, mounting these steel plates can create a
"bounce back" hazard as well. A classic example is the steel target plate welded to a "foot" that is then placed on a pedestal. If the "foot" extends beyond the plane of the target surface it will direct fragments uprange. My wife got hit in the neck with a jacket frag from one of these targets at an indoor pistol match and since then I've been on a crusade to educate range personnel whenever I see these type of targets.
The target in this video is an example of a steel target system that is designed for safety.
The target is not rigidly mounted and has freedom to move... a lot.

The plate hangs on a back angle.
The mounting bolt head is rounded and low profile.

The target plate is in front of the T Post enough to mitigate fragments from contacting the post.
