It's pretty informal. the 150 yard targets range from 16X24 down to a 3" plate. Out about 500-600 yards we put a 30X30. If I remember the scoring was 10000 points for the big rectangle, 15000 for the 16" round, 25000 for the 6" pipe, 50000 for the 8" plate and 100000 for the 3" plate, 500000 for the 600 yard target. double points if you call your shots. 1000 points for hitting the hillside. 12 rounds per shooter.  All the info is on the site, look at the photos and you will get the idea. Look around the range for anything close. We would be happy to help out, I might even show up!
