Zeroing Your RifleZeroing simply means to set the point of impact at the point of aim at a certain distance. This distance, called the "primary zero", is the where the bullet will impact where the cross-hairs are pointed, when the elevation and windage knobs are zeroed out and have no adjustments applied.
I recommend using a 100-yard zero instead of a longer-distance zero for several reasons. First, any wind that is present will have a very small affect on the zero. Second, if you are "off" in distance by up to 10 or 15 yards, the effect on your zero will be minimal. For example, if you're actually shooting at 90 yards or 110 yards instead of 100 yards exactly, the difference in point of
Open land for shooting can be hard to find. Public lands are often the only place to shoot beyond 200 yards.
Finding a RangeIn many parts of the country, finding a rifle range longer than 200 yards is difficult. Even with an established range, you are normally limited to shooting from the defined "bench" shooting area, giving you essentially one shoot position on a known distance (KD) range. One way to get access to good field-style shooting is to attend a national-level match of that type. Examples include Colorado Multi-Gun's Practical Rifle Team Challenge, and the Blue Steel Ranch Steel Safari.
Unless you have access to thousands of acres of private land where you can shoot, the best bet is to find public lands where target shooting is legal. For example, in most National Forests, shooting is legal as long as you follow some simple rules and clean up after yourself.
Locating targets can be extremely difficult and is an acquired skill. Five targets here are circled in red.
Targets and PlacementObviously the first priority needs to be safety -- be sure of what is behind your target, and that there is enough empty to ensure safety.
I recommend shooting at armor steel (AR400 or AR500) steel plates, hung from conveyor belt strap. If they are one a metal stand, make sure some "play" is available. This will make the steel "ring" to indicate a hit, and help to reduce ricochets.
For practice, I recommend placing hanging steel plates in front of a hillside of rock or dry dirt. This will make it easier to spot misses, since the dust will be readily visible and its location can be easily determined relative to the target. If the target is on the top of a hill or a totally flat location, or in front of bushes or trees, it can be very difficult or impossible to spot misses. (When setting up a match, do not follow those guidelines-- don't want to make it too easy for the shooters!)
Place targets at arbitrary and irregular distances. This makes the shooters actually range the targets and not just guess knowing that you set targets every 50 yards, and do some interpolation of their data card compared to the actual distance.
