This works as well for hunters as competition shooters, but I wasn't sure where to put it. One of the guys at the club I shoot at came up with a way to check what you need to dial (mils or moa) for 300 and 600 yards when you only have a 100 yard range to shoot at. I used it this afternoon to check against what the ballistics program I use said my "come-ups" should be for those distances. According to the ballistics program, 4.2 moa was needed for 300 yards and 13.9 moa was needed for 600 yards with the bullet/velocity being shot. Actual 300 moa was 5 and 600 was 13.5 moa.
The target is made with dots at the bottom to verify your 100 yard zero. Measure up 5 inches from the center of the dot and mark for your 300 yard POI. Measure up 16 inches from your 100 yard zero for your 600 POI. This will be pretty close for any caliber you are shooting. I saw it used for everything from a .223 to a 30-338 at a sight-in clinic I was an instructor at last Monday evening. You should use a ballistics program to have an idea how much you will need to dial to get close to what the 300 and 600 yard dots represent.
Here is a picture of the target I made for the test. I'm glad there is a range of 600 yards at our club to verify these numbers.
