Almost all of the tactical rifle drills I run involve movement to target, forward and lateral shooting, engaging multiple targets, barricade shooting, strong and support side transitions, primary to sidearm transitions etc, all pretty dynamic stuff.
I've developed a drill I call the Wounded Man Drill, which presumes you have been knocked down or injured and involves various positions and one-handed sidearm engagement from both strong and support sides, but I don't recommend it unless the shooter has plenty of experience on tactical or combat courses.
If you have your own range, start with simpler stuff, like a 1 through 5 drill. Set up three silhouettes abreast and engage from 20-30 yards, and time yourself or have someone time you...1 shot in the first target, 2 shots in the second, 3 in the third, 4 back in the second target and 5 back in the first target. A good beginner time on that drill would be all 15 rounds on the assigned targets in about 4.5 seconds. As you get more used to it, you can expand your range and add drills involving movement, etc.
