The .308 Winchester caliber is a popular choice for long-range shooting, hunting, and tactical applications. Achieving accurate shots at distance requires precise zeroing of your rifle scope. This is where a .308 bore sighting laser comes in. This guide provides a comprehensive overview of bore sighting lasers, focusing on their benefits, how they work, and what to consider when choosing one for your .308 rifle.
What is a Bore Sighting Laser?
A bore sighting laser is a tool designed to quickly and easily align your rifle scope with the bore (the barrel) of your firearm. Instead of firing numerous rounds to roughly zero your scope at the range (which wastes ammunition and time), a bore sighting laser allows you to get very close to the desired point of impact before you even reach the range. For the .308, this is particularly beneficial due to its recoil and the cost of ammunition. The laser projects a beam that simulates the path of the bullet, significantly reducing the time and effort required for initial scope alignment.
How Does a .308 Bore Sighting Laser Work?
A .308 bore sighting laser typically consists of a small laser unit that is inserted into the barrel of your rifle. The laser emits a visible red or green dot that is projected onto a target. By adjusting your scope's turrets, you align the crosshairs with the laser dot. Once aligned, you'll be much closer to being zeroed at the range, requiring minimal adjustments. This process is far more efficient and less wasteful than traditional methods.
Different Types of Bore Sighting Lasers:
Several types of bore sighting lasers exist, each with its pros and cons:
- Battery-powered lasers: These are the most common type. They require batteries and offer a visible beam for alignment.
- Fixed lasers: These are permanently installed in the rifle's barrel and don't require batteries. However, they are less versatile.
Benefits of Using a .308 Bore Sighting Laser
- Saves time and ammunition: Significantly reduces the time and ammunition required for initial scope zeroing.
- Improved accuracy: Facilitates more precise scope alignment leading to better shot grouping at longer ranges.
- Cost-effective: While the initial cost of the bore sight laser needs to be factored in, the long-term savings on ammunition can be substantial.
- Safer: Reduces the risk of accidental discharge during the initial zeroing process.
- Easier to use: Simple to use, even for beginners.
Choosing the Right .308 Bore Sighting Laser
When selecting a .308 bore sighting laser, several factors should be considered:
- Laser color: Green lasers are generally preferred as they are more visible in various lighting conditions compared to red lasers.
- Battery life: Look for a laser with a long battery life to ensure you can complete the bore sighting process without interruptions.
- Durability: Choose a laser constructed from robust materials to withstand the rigors of use.
- Compatibility: Ensure the bore sight laser is compatible with the caliber of your rifle (.308 Winchester).
- Adjustability: Some lasers offer adjustable brightness for various conditions.
Safety Precautions When Using a Bore Sighting Laser
- Always treat your firearm as if it were loaded.
- Ensure the firearm's safety is engaged.
- Wear appropriate eye protection.
- Never point the laser at yourself or others.
- Only use the bore sighting laser in a safe environment.
- Follow the manufacturer's instructions carefully.
Conclusion
A .308 bore sighting laser is a valuable tool for any .308 rifle owner. By quickly and accurately aligning your scope, it saves time, ammunition, and ultimately leads to better shooting accuracy. However, safety should always be the top priority when handling firearms and bore sighting lasers. By understanding the benefits, choosing the right tool, and following safety protocols, you can maximize the effectiveness and safety of using a bore sighting laser for your .308 rifle.
