I am in general a fan of watching myself shoot on video. Not for the vainglorious reasons, but rather because it gives me an opportunity to critique my performance from outside my body. I can’t see my body mechanics and presentations when I’m shooting, so the only feedback that I have is my front sight and the target results. One thing I do recommend is to allow some time to pass in between when the video was filmed and when you go back and watch the tape. You need to be able to look at it with fresh eyes that aren’t still dwelling on how good/bad the performance was. For example, the video below was shot at the end of July – sufficient time has passed that I can watch those two stages and look at my performance and think “why did I do that?” in a couple of key areas.
There’s a reason that professional athletes watch film of themselves – even amateur athletes and C-class shooters can benefit from it as well.
