One of my favorite daydreams is a small piece of land in the country, a modest cabin, and my own personal rifle range.
Of course, I would build a shelter from which to shoot. It would be roomy enough for myself and a few friends, and it would include a grill for cooking and handwarming in cold weather.
What about sound attenuation? Let's assume the nearest dwelling is 500 yards away. As a good neighbor, I would want to reduce the noise level as much as possible. How would I design the shooting shack to achieve this?
