It is my feeling that practical shooting competitions are a good place to see what works and what does not with out finding out something was a bad idea the hard way. For example, I learned in competition that I need to make my front sight post a different color than my brush guards so that I don't mistake a brush guard for the front sight again. In competition it is no problem but in real life it can be unpleasent.

If you have leaned something in competition that directly translates to the real world please post.
