The process of modifying a Bushnell riflescope’s settings to align the reticle with the point of impact involves manipulating the elevation and windage turrets. For example, one might need to compensate for the trajectory of a bullet over distance by adjusting the elevation, or for lateral drift caused by wind by adjusting the windage. This precise alignment ensures accurate shot placement at varying ranges and under different environmental conditions.
Accurate shot placement is crucial for ethical hunting, competitive shooting, and overall firearm proficiency. This process allows shooters to compensate for various factors that influence bullet trajectory. Historically, scope adjustments were cruder, requiring tools and lacking the precision offered by modern, easily adjustable turrets. The ability to fine-tune a scope quickly and effectively in the field significantly enhances a shooter’s capability and effectiveness.
This article will explore the intricacies of scope calibration, covering topics such as understanding MOA (Minute of Angle) adjustments, performing bore sighting, using a shooting rest for accurate adjustments, and troubleshooting common issues. It will also offer guidance on maintaining a Bushnell scope to ensure long-lasting performance and accuracy.
1. Understanding MOA Adjustments
Understanding Minute of Angle (MOA) adjustments is fundamental to effectively zeroing a Bushnell scope. MOA is an angular measurement representing approximately one inch at 100 yards. Each click on a Bushnell scope turret typically corresponds to a fraction of an MOA, such as or MOA. This means a MOA adjustment will move the point of impact inch at 100 yards, inch at 200 yards, and so forth. Without a firm grasp of MOA, the shooter cannot accurately predict how turret adjustments will translate to changes on target. This understanding forms the basis for making precise adjustments and achieving a properly zeroed scope.
For example, if a shot impacts two inches low and one inch right at 100 yards with a scope featuring MOA clicks, the shooter needs to adjust the elevation eight clicks up (2 inches / inch per click) and four clicks left (1 inch / inch per click). Attempting these adjustments without understanding MOA would be guesswork at best. This knowledge also enables the shooter to compensate for bullet drop at longer ranges. Knowing the bullet’s trajectory and the scope’s MOA adjustments, the shooter can accurately dial in the necessary elevation to compensate for the drop and hit the target at extended distances.
In summary, a thorough understanding of MOA is not merely helpful but essential for precise scope adjustment. It transforms the process from trial-and-error into a predictable, repeatable procedure grounded in mathematical principles. Failure to grasp MOA can lead to frustration, wasted ammunition, and ultimately, inaccurate shooting. Mastering this concept allows the shooter to fully utilize the capabilities of their Bushnell scope and consistently achieve accurate shot placement.
2. Proper Sighting-In Techniques
Proper sighting-in techniques are inextricably linked to successful scope adjustment. They provide the framework for accurately interpreting and implementing the necessary adjustments. Without a methodical approach to sighting-in, even precise adjustments become meaningless. Sighting-in involves firing a series of shots at a known distance, typically 100 yards, and observing the point of impact relative to the aiming point. This information informs subsequent scope adjustments, creating a feedback loop that progressively aligns the reticle with the point of impact. Using a stable shooting rest and consistent aiming practices minimizes shooter-induced errors, ensuring adjustments reflect the scopes performance, not inconsistencies in shooting form. For instance, failing to use a proper rest can introduce canting or movement of the rifle, leading to inaccurate shot placement and consequently, incorrect scope adjustments.
Several techniques exist for sighting-in a riflescope, each with varying degrees of complexity. The most common involves firing three-shot groups and adjusting the scope based on the average point of impact of each group. More advanced techniques, such as using a bore sighter for initial alignment, can expedite the process. However, all effective techniques share common elements: a stable shooting platform, consistent shooting form, and a methodical approach to interpreting and implementing adjustments. For example, a shooter might initially bore sight the rifle to roughly align the scope with the barrel. Subsequent live fire at the range will then fine-tune the zero using the three-shot group method. This combined approach saves time and ammunition.
In summary, proper sighting-in techniques are not merely a prerequisite to scope adjustment, but an integral part of the process. They provide the necessary feedback loop that allows for accurate interpretation and implementation of scope adjustments. Ignoring these techniques risks misinterpreting shot placement, leading to inaccurate adjustments and ultimately, a poorly zeroed scope. Consistent application of these techniques, combined with a thorough understanding of MOA adjustments, ensures the riflescope’s full potential is realized, yielding accurate and predictable shot placement.
3. Consistent Shooting Form
Consistent shooting form is paramount when adjusting a Bushnell scope. Inconsistencies in stance, grip, breath control, and trigger pull introduce human-induced errors that obscure the true point of impact. This makes it difficult to determine whether shot deviations result from scope misalignment or shooter error. For example, inconsistent cheek weld on the stock can alter the shooter’s eye position relative to the scope, causing vertical stringing of shots and misleading the shooter about necessary elevation adjustments. Similarly, erratic trigger pull can induce horizontal dispersion, leading to incorrect windage adjustments. Essentially, inconsistent form renders the process of scope adjustment unreliable.
The relationship between shooting form and scope adjustment is symbiotic. One cannot effectively adjust a scope without maintaining consistent form, and conversely, even a perfectly adjusted scope is rendered useless without proper shooting techniques. Consider a shooter who consistently pulls the trigger to the right. This will result in shots impacting right of the intended point of aim. The shooter might then adjust the windage to compensate, creating a zero that is only valid for that specific flawed technique. If the shooter later corrects their trigger pull, the zero will no longer be accurate, leading to missed shots. This illustrates the crucial need to address fundamental shooting mechanics before attempting scope adjustment.
Accurate scope adjustment hinges on eliminating all variables except those directly related to the scope itself. Consistent shooting form eliminates human-induced variables, allowing for a clear assessment of the scope’s performance and accurate adjustments. Failure to address inconsistencies in form can lead to a frustrating cycle of adjustments and missed shots, as the shooter attempts to compensate for their own errors rather than correcting the scope. Mastering consistent form not only enhances accuracy but also provides a stable foundation for scope adjustment, ensuring the adjustments made are valid and reliable across various shooting scenarios.
Frequently Asked Questions
This section addresses common queries regarding Bushnell scope adjustments, aiming to provide clear and concise answers for enhanced understanding.
Question 1: How often should a Bushnell scope be re-zeroed?
