I'm forking this discussion off from a defensive-related thread. Let's discuss RUNNING: movement to minimize the time we spend not shooting. There are some interesting questions, and I hope @RJ doesn't mind me using his post to motivate the discussion.
When do we reload? This depends on the length of the movement, and other factors like position relative to the safe angle.
How do we learn to RUN* with a loaded gun? What are some good drills for learning to run as fast as possible, while also being safe?
*like you're in a race or someone is kidnapping your kid
What are some approaches to running while retreating? How do we approach the reload during these movements?
Etc...
GO!
