![]() H.25 Property Title to any budgeted and approved equipment purchased by the Subcontractor shall vest with the Subcontractor subject to any subsequent disposition instructions provided to Parallax by the State of Ohio. Parallax may terminate this Subcontract by issuing Subcontractor written notice of the termination, specifying the extent of the termination and the effective date. H.10 Limitation of LiabilityTo the maximum extent permitted by applicable law, in no event shall Parallax or Subcontractor be liable to the other for any special, incidental, consequential, or any other type of indirect damages arising out of or related to this Subcontract, or the breach of any terms thereof, under any theory of law or equity, even if that party has been advised of the possibility of such damages.Įmail submissions are desired as long as Subcontractor ensures the submission is received by Parallax. Use a fine paint marker to mark the point on your ring or turret for this range.Parallax may terminate this Subcontract in whole or in part if it determines that a termination is in its best interests or if the State of Ohio exercises its termination-for-convenience rights under the Contract.Use the parallax compensation turret or objective ring to adjust the focal planes until there is no movement of the reticle when you shift your gaze.Slowly shift your gaze while looking for movement of the reticle in relation to the target.Preferably this is 1,000 yards, although shorter distances also work. Make sure your target is the maximum distance possible at your shooting range.Set up the firearm in a stable configuration aimed downrange at your target using sandbags or a machine rest.Make sure your scope has been zeroed for your rifle.To get consistent compensation, start with the adjustment knob or ring set on the stop past “infinity.” Some adjustment systems, such as a side-mounted turret, have knobs you can use to “re-zero” the mechanism. To measure the actual parallax compensation needed for a given distance and zoom, head out to a range with known distances and calibrate your parallax adjustment mechanism. Most tactical scopes are not long enough or powerful enough to exhibit parallax. Once the zoom is increased to 20x, it takes a very fine adjustment to completely eliminate it. Why is it so critical to get a precise compensation setting?īecause the amount of parallax increases with magnification, giving you a larger margin of error at higher powers if it is not precisely corrected.įor example, on a high-power variable 6-20x magnification scope, parallax appears easy to compensate for at the lower 6x magnification setting. I find it helpful to manually determine the proper setting at 50-yard increments and mark those settings on the scope. While helpful as a general starting place, these factory set markings are not always accurate. Some of these rings or turrets are marked with various distances, generally ranging from 50 yards to infinity, indicating the proper setting to eliminate parallax. High-power scopes are usually equipped with a side-mount turret, or adjustment ring located on the objective bell, so you can move the focal plane of the target and reticle and eliminate parallax. In high-power scopes used over long distances, you must compensate for parallax. Parallax is usually negligible or not present at all in most low-magnification tactical style scopes, as the scope is too short or the range is not long enough.ġx red-dot style scopes generally are parallax-free at any range.Įven mid-power hunting scopes have very little parallax, and many tactical models do not have parallax compensation, as it is impossible to quickly and accurately determine range in a dynamic tactical situation. The problem occurs when your line of sight is not exactly lined up, as the point of aim indicated by the reticle is now incorrect.īy eliminating parallax and having the target image and reticle on the same plane, you no longer have to have a precise line of sight: no matter what angle you are looking through, the scope at the reticle will still accurately indicate the correct point of aim. It is possible to have an accurately-placed reticle in the first scenario if you are looking through the scope with your line of sight exactly lined up with the reticle and target image. When the focal plane for the target image and the reticle are the same, no parallax adjustment is necessary. When the angle at which you are viewing the image through the eyepiece changes, the reticle position relative to the target image changes. ![]() The point where the focal lines cross and form an X is the focal plane for the target image. When shooting long distances, it is important to account for parallax. ![]()
