How to set my bushnell scope 3-9x40 for 200 yards
The Bushnell 3-9X40 has been around for quite some time in several forms, but it is pretty standard to set it like any other scope.
With the gun resting solidly on sand bags or something like a Lead Sled, shoot at a target with a 1" grid on it. Those targets are a free download at http://targetz.com/, but you have to browse to find them. Targets No: 10049 or 10058 are both usable, if you can see a 1" aiming point with a 9 power scope at 200 yards.
With a known point of impact (POI) at 200 yards, you can move the POI to where you want it (inside the caps at the center of the scope, there are adjusting screws or slots). The norm is 1/4" per click (the adjuster can usually be felt to click) at 100 yards or four 1/4" clicks for an inch. At 200 yards, the adjustment will be twice what it is at 100 yards or 1/2" per click.
Make your adjustments, using the grid on the target to tell you how many inches it needs to move, and shoot the target again to confirm the adjustment is correct. It's pretty standard to shoot at least a three shot group to ensure the bullets are reasonably close to each other.
Another method is to set the POI at a certain number of inches high at 100 yards and assume it's right at 200 yards. If the mid range trajectory, for your cartridge, at 200 yards is X inches high at 100 yards, you can set your POI to that X inches high and be pretty close at 200 yards.
