With the help of Stephen Hogan, the Chief Range Officer on Range 4, I was able to get full access to the firing line during the first relay (experts) on 45 day. I was able to take a number of photographs which are posted at http://photos.yahoo.com/clark2245 , along with these videos.

This video shows two shooters doing timed fire. The one on the right is John Hall.

This one is of two more shooters doing rapid fire with the 45. You can hear firing start up in the background on range 3.

This one has another view of a group of shooters doing timed fire on range 4.

When we go down to score targets, the adjacent ranges are sometimes firing, which has always been a little bit of an odd feeling for me. Especially when they are all the way back at the 50 yard line. This is a view from the practice line on range 2 of shooters on range 3 doing timed fire on 45 day.
