The Sporting Rifle Match is one instance of the "hike and shoot" practical rifle matches, which have been around in various forms for many years (Keneyathlon, Cooper Rifle Walk, Steel Challenge, PRTC, ITRC, "Sniper" matches, etc).
At the SRM, we have ten stations spread over a two mile distance in the terrain of the North side of the NRA Whittington Center. At each station there are six different targets, again spread out in the terrain (within maybe a 30-40 degree shooting zone) from as close as 100-some yards out to about 700 yards. You get one shot per target, but we tell you the distance. Having everyone range every target would slow down this match too much.
Targets are all hanging armored steel which swing and "ring" when they are hit. Target shapes vary, including circles, rectangles, diamonds, and squares. Apparent target size ranges from about 2 MOA to maybe 4 MOA, with physical sizes ar 6" to 14", I think.
Each station has a steel post stuck in the ground, and the shooter has to be able to touch that post while engaging the targets. He can use whatever position he wants to, and at many of the positions, prone is impossible due to the target position compared to grass and shrubs.
Here are pictures we took at some of the matches over the last three years (when I remembered bring my camera!)
You can see people are using all kinds of gear. This is a tough match, nobody has ever cleaned it yet.
