Reticle Canting in Relation to the Rifle’s Bore
Even with a level reticle within the scope body, the scope itself can be misaligned relative to the rifles bore. This misalignment will result in vertical point-of-impact shifts as the distance to the target increases. For instance, a scope canted slightly to the left will cause shots to impact high and to the left at longer ranges. Precise mounting techniques and careful alignment procedures are critical for minimizing this type of error. This alignment is typically checked during the boresighting process and refined during live-fire adjustments.
-
Illuminated Reticle Alignment
For scopes equipped with illuminated reticles, verifying proper illumination alignment is essential. The illuminated portion of the reticle should be centered and consistent in brightness across its entirety. A misaligned illuminated reticle can create aiming offsets, particularly in low-light conditions. For example, an off-center illuminated dot could lead to shots impacting slightly off the intended point of aim. Checking illumination alignment typically involves observing the reticle against a dark background at varying brightness settings.
-
Consistent Reticle Position through Magnification Changes
The reticle should remain centered and consistent in its position throughout the scope’s magnification range. Any shift in reticle position during magnification adjustments indicates a potential internal misalignment. This can result in point-of-impact shifts at different magnification levels, affecting accuracy and making it difficult to maintain a consistent zero. This is checked by observing the reticle’s position on a fixed target while adjusting the magnification from its lowest to highest settings.
In summary, meticulous reticle alignment is paramount for precise shooting.

Each facet of reticle alignment contributes to a consistent and predictable point-of-impact, ensuring that the riflescope performs as intended and facilitates accurate shot placement in various shooting scenarios. Therefore, reticle alignment checks are integral to any comprehensive riflescope evaluation, contributing to a more effective and reliable sighting system.
4. Tracking Accuracy
Tracking accuracy, the ability of a riflescope’s adjustments to correspond precisely to point-of-impact changes on the target, is crucial for maintaining zero and making accurate long-range shots. Verification of tracking accuracy is an essential component of checking a riflescope. This process involves systematically adjusting the turrets through a known value, typically measured in Minutes of Angle (MOA) or Milliradians (MRAD), and observing the corresponding shift in point-of-impact on a target at a known distance. Discrepancies between the intended adjustment and the actual point-of-impact shift indicate tracking errors. For instance, if a 1 MOA adjustment to the elevation turret results in a 0.8 MOA shift on the target, the scope exhibits a tracking error. This error can accumulate over larger adjustments, leading to significant inaccuracies at longer ranges.
The practical significance of tracking accuracy is readily apparent in long-range shooting disciplines. Consider a scenario where a shooter needs to adjust their point-of-impact by 10 MOA to compensate for bullet drop at an extended distance. A scope with accurate tracking will reliably shift the point-of-impact by the desired amount. Conversely, a scope with tracking errors may result in a shot impacting high or low of the intended target, even with the correct adjustments applied. Therefore, confirming tracking accuracy is paramount for achieving consistent, predictable results, especially in scenarios requiring precise long-range adjustments. This is often achieved through a “tall target test” or “box test,” where the shooter fires a series of shots while systematically adjusting the turrets and observing the resulting pattern on the target. Any deviation from the expected pattern signifies a tracking error.
In conclusion, accurate tracking is integral to riflescope precision and reliability. Checking tracking accuracy provides critical insights into the scope’s ability to perform as intended. Identifying and addressing tracking errors, whether through repair or compensation, is essential for maximizing accuracy and achieving consistent results, particularly in long-range shooting.
