paper dinner plates work well also, but aren't as "eye catchy" (too say nothing of cheaper) and they don't need taped.
Surrender, hands up, with back to target, was an old standards, still useful
If possible shoot what ever practice you do choose, with weak hands as much as possible.
Use a 180 deg. range if possible, which allows targets at 90 to 180 deg sweep
use range that has firing line movement. not target. In other words you move to the target rather than moving the target near and far. Take an old door. for barricade practice.
