They are called "powder actuated tools" and they'd be perfect for what you describe. There's a wide range of loads and pins. It may take some experimenting to get it right. You'll want to shoot the pin thru a steel disk, thru the copper and into the steel. I'd try a rental yard first - they are expensive to buy, for one job. If that's a dead-end call up some drywall contractors. They all do steel-stud interior partitions and they gotta have a pin-driver for that.
