I've only run and shot one match, so take this as you will, but we did go out to 300 meters on the last stage. I had people worried about that distance, so provided all kinds of dope for the shooters the day before. The really long stage was last and had two different targets you could shoot at: a 24"x24"x1/8" square and a 2/3 IPSC. Shooters choice with, the IPSC worth 2 points vs the 24" square at 1 point. at least half of the shooters made good impacts with a few gaining extra points on the IPSC.
However, the favorite stage of many was a stage at 200 yards where I hung up shaving cream cans from the dollar store at different heights on a rack. Shooters got 3 attempts at the can with a 1st round hit = 12 points, a 2nd round hit = 6 points and a 3rd round hit = 3 points. Of course the shaving cream spins and spews cream when hit. This was a favorite of the younger shooters, with most of them doing better here than on some easier stages due to the fun factor.
Good luck with your match! I had enough fun with that one, that I plan on another in the cooler season here, when we are limited to 300 meters because of hunting season in the area.
