I have made some progress on my range. I'm working a lot of hours so time has been limited.
The carport is a 18x21 7ft tall. You can see some if my USPSA props. It will serv as a covered shooting line for airguns and also for USPSA Dry fire.
The front of the carport will be 45 yds to the mount for falling rams. That's the official distance for airgun sillhouette. The back of the carport will be 50 yds to paper targets at the wall. The steel will be a couple feet from the wall so that gives me the room needed to stay covered by the carport @ 45 and 50yds
