Practice makes perfect

Hey Guys,
You've all heard the saying that practice makes perfect. Well I've got a membership to the local gun range and I'm going to be doing some practice with airsoft guns. Most of it will be within 75 feet. I was just going to ask your suggestions for practice items and techniques.

My plan:
Set up milk jugs and other such targets in different configurations. There are moveable benches and tables at the range to use as stands, cover, and obstacles. Get the "scenario" set up. Start a stop watch and try to knock down the targets as quickly as possible, with limited rounds and forced magazine changes every X targets.

I'm hoping that this will help my snap shooting and my magazine changes as well as target acquisition and transition. If I get it working well then maybe some guys can come out there with me during the week and we can bring out some pizza or something and run speed competitions.

Any suggestions for ways I can practice my airsoft shooting at the range? Ideas?
