Re: sniper golf
In 2007 we had the West Coast Tactical match south of Cheney, WA in some nasty scab rock canyons. Targets were steel targets, and shots varied from 140 yds at a 30 deg. down angle to 900+ yards. The course designers used the terrain very effectively to screw with the shooters (target might be out on a 'finger', with another 'finger' in front of it, but not visible from the shooters position so it looked like they were all on one plane - but any misses just 'disappeared'). Scoring was 50pts 1st round hit, 30 for 2nd, 20 for 3rd (max three shots allowed). Shooters got a sheet with each of five stations listed on it, and 3-4 compass bearings for each station. The compass bearings were to the targets (still had to find them in the trees & rocks) but only from that specific station. Two man teams, central control, movement between stations only when the range was confirmed 'cold', and shooting recommenced once everybody was in place and accounted for. One of the most aggravating (I was shooting a .308, and my buddies' gun wasn't working as advertised...), and fun matches I've shot in a while.
Locally (East Wenatchee, WA) we have a 'practical rifle' match every year. Not really a 'sniper' match, but not BR or F-Class either. Cold bore shots, 300yd group, 600yd steel, 450yd bowling pins, barricade shots, etc. Our scoring there is however you happen to score on an individual stage (say 4 out of 5 pins gets you 5th for that stage), thats your 'score' : 5pts. First place gets 1pt. 18th place gets 18 pts. Low agg for the day wins. Its entirely possible to win the overall match without winning any one stage, just staying consistently second or third and not having any train wrecks. Rewards consistency rather than someone who does really well on one stage and craps out on another.
