Choosing the right laser bore sighter is crucial for achieving accurate zeroing with your .45-70 firearm. This comprehensive guide will delve into the specifics of 45-70 laser bore sighters, helping you select the best tool for your needs and ensuring your shots land where you intend them to.
Understanding Laser Bore Sighters
Laser bore sighters are invaluable tools for firearm enthusiasts and professionals alike. Unlike traditional methods, they provide a quick and efficient way to roughly align your firearm's sights with its barrel. This preliminary alignment significantly reduces the time spent at the range, saving ammunition and accelerating the zeroing process. A 45-70 laser bore sighter specifically caters to the larger caliber of the .45-70 cartridge.
How Laser Bore Sighters Work
A laser bore sighter is a device that fits into the barrel of your firearm. It projects a laser beam that mirrors the trajectory of a bullet fired from the same barrel. By observing the point of impact of the laser, you can adjust your sights accordingly, bringing your point of aim and point of impact into closer alignment before live fire. This greatly simplifies the process of zeroing your rifle or pistol.
Key Features to Consider When Choosing a 45-70 Laser Bore Sighter
Several factors contribute to the effectiveness and usability of a laser bore sighter. When choosing a 45-70 laser bore sighter, prioritize these features:
1. Caliber Compatibility:
Ensure the bore sighter is explicitly designed for the .45-70 caliber. Using an incompatible bore sighter can damage your firearm or provide inaccurate results. The diameter of the bore sighter must precisely match the bore of your .45-70 rifle or pistol.
2. Laser Power and Visibility:
A brighter laser is easier to see, particularly in bright sunlight. Consider the environmental conditions where you'll be using the bore sighter and choose one with sufficient laser power for optimal visibility.
3. Battery Life:
Longer battery life is a significant advantage, allowing for extended use without interruption. Check the manufacturer's specifications for battery life and consider the type of battery used (e.g., replaceable vs. built-in).
4. Durability and Construction:
The bore sighter should be constructed from durable materials capable of withstanding the rigors of handling and occasional drops. A robust design ensures the longevity of your investment.
5. Ease of Use:
A well-designed bore sighter should be easy to insert and remove from the barrel of your firearm. The user interface for adjusting the laser (if adjustable) should be intuitive and straightforward.
Using a 45-70 Laser Bore Sighter: A Step-by-Step Guide
- Safety First: Always treat your firearm as if it were loaded, even when using a laser bore sighter. Ensure the firearm is unloaded and the action is open.
- Insert the Bore Sighter: Carefully insert the laser bore sighter into the barrel of your .45-70 firearm, ensuring a snug and secure fit.
- Adjust your Sights: Aim the firearm at your target (a suitable target at a known distance). Observe the point of impact of the laser and adjust your sights (rear and front) until the laser impacts where you want your bullet to hit.
- Test Fire (at the Range): After adjusting the sights, proceed to the range to fine-tune the zero using live ammunition. The laser bore sighter provides a starting point, but fine adjustments are often necessary.
- Proper Storage: After use, clean the bore sighter and store it in a safe and secure location to protect it from damage and ensure its longevity.
Conclusion: Selecting the Right Tool for the Job
Choosing the right 45-70 laser bore sighter significantly streamlines the zeroing process. By considering the factors outlined above and following proper usage guidelines, you can ensure your .45-70 firearm is accurately zeroed and ready for use, whether for hunting, target shooting, or other applications. Remember that a laser bore sighter is a tool to assist in the initial alignment; always verify zeroing at the range with live fire.
