No need for any devices to hear music at the range.
Setting up I can hear the 1812 overture playing in my head.
For some reason it goes well with the background noise from the skeet range.
Leaning in over the scope for the first shot off the bench
the opening riff from Thunderstruck takes over,
and by the time I finish the first box I find myself hearing Riders on the Storm.
The back beat fits the bolt motions and chambering of cartridges.
What? Doesn't everybody? The rhythm is there, you can feel it.
Slows the heart rate down and improves my focus.
