How Accurate Is Bushnell Bore Sighter

How Accurate is a Bushnell Bore Sighter?

Are you considering using a Bushnell bore sighter to zero your rifle scope? It's a popular and convenient tool, but how accurate is it really? Let's delve into the accuracy, limitations, and best practices for using a Bushnell bore sighter.

Understanding the Bushnell Bore Sighter

The Bushnell bore sighter is a simple device designed to get you on paper quickly. It fits into the barrel of your firearm and uses a laser to project a point of aim. This allows you to roughly align your scope with your barrel before moving to the range for fine-tuning. It's not designed for precision, but as a convenient starting point.

Accuracy Expectations: What to Expect

The key takeaway is that a Bushnell bore sighter provides a rough estimate, not precise zeroing. Think of it as a tool to get you close—perhaps within a few inches at 25 yards—rather than a substitute for proper range time with live ammunition. Factors affecting accuracy include:

• Barrel Differences: Variations in barrel manufacturing can slightly alter laser projection.
• Laser Alignment: Imperfect seating of the bore sighter can affect the laser's path.
• Scope Mounting: Incorrect scope mounting will always introduce error, regardless of your sighting method.

Don't Expect Miracles: The Reality Check

While the bore sighter can save you time at the range by getting you on the target, it won't get you on target with precision. Expect to need several adjustments at the range using live ammunition to fine-tune your scope's zero.

Optimizing Bore Sighter Usage for Best Results

To maximize the accuracy you can achieve with a Bushnell bore sighter, follow these tips:

• Proper Seating: Ensure the bore sighter is firmly seated and centered in your barrel.
• Stable Platform: Use a stable rest or shooting bench to maintain consistent alignment.
• Safe Handling: Always follow firearm safety protocols.
• Multiple Shots: Use the bore sighter from several positions to get an average point of impact.
• Range Time is Essential: Remember the bore sighter is only a starting point. Range time with live ammunition is crucial for accurate zeroing.

Alternatives and When to Use a Bore Sighter

A bore sighter can be a helpful tool under certain circumstances. It's particularly convenient when:

• You're short on time: It can get you close enough to minimize the time needed at the range.
• You're new to firearms: It can help you learn the process of zeroing a scope.
• You need to quickly align a scope: If you're changing scopes frequently, it might save time.

However, experienced shooters might find it unnecessary, opting for other zeroing methods from the start.

Conclusion: A Useful Tool, But Not a Replacement for Proper Zeroing

The Bushnell bore sighter is a valuable tool to accelerate the zeroing process, but it is not a substitute for precise zeroing using live ammunition at the range. Understand its limitations, follow best practices, and always prioritize safety. With realistic expectations, you can use it to enhance your shooting experience.
