OK, I guess I should be a bit more constructive.

A couple of very minor changes would make the whole show a lot safer:
1. Load the firearm behind the line if necessary, but leave the action open. Do not move to the line with the firearm bombed-up with action closed and off-safe. Close the action and commence fire when the start whistle sounds, action remains open up till the whistle.
2. Move only with action open. Reloading can take place on the run, but close the action only when stationary and about to engage the next target.
3. Clear firearms and show safe at the conclusion of each serial.

Other than that, it looks like a great course and would no-doubt be very educational for those who have never had to reload on the run or shoot big-bores fast!
