I don't know if this is the right forum to put this because it's not a drill, test etc it's more of a question.
Short version of the question is this:
If you have a new shooter, someone that isn't terribly interested in much practice or just doesn't have the time for it, what is a dry fire drill they should do?
The 15 minutes is kind of aribitary I know so if you think there's something that takes 20 minutes and is dramatically more efficient go for it. I'm mainly looking for the best bang for your buck in terms of time.
I'm sorry if this has been covered before but my searching got a lot of results so hard to tell what is legit.
