No soundtrack to my shooting
Shooting at the range is lots of fun, yes, but it is also the deadly serious business of preparing to defend my life and the lives of those I love.
Too serious to set to music - that would make it too much like the soundtrack to my own private action movie.
Besides, who needs the distractions? Shooting well is about FOCUS, and you can't do that as well as you need to if even part of your mind is off singing along.
