They seem like a pretty terrible shooting target. A flat piece of steel angled down will controllably direct the rounds into the dirt. A round target is going to ricochet everywhere.
Truth to this, bullets will ricochet off of round steel very easily.
If you do not know what was in them do not attempt to cut them. Acetylene gas can remain in there, not sure about Oxygen cylinders what they are like to cut. The only ones I know 100% for sure you could cut would be Carbon Dioxide and Nitrogen tanks and at that make sure they are completely empty. I recommend an abrasive wheel in a grinder, sawzall blades will just skip across the steel.
I would take them to a gas company for disposal or to ask them what you can do with them.
