Key Takeaways

• First and second focal plane rifle scopes differ in where the reticle appears in relation to the erector system within the scope.
• First focal plane scopes are generally more expensive than second focal plane scopes but offer advantages such as precise holdovers at any magnification setting, consistent reticle size, and accuracy for long-range shooting.
• In contrast, second focal plane scopes are popular among hunters due to their static reticles, making sighting in easier and windage/elevation adjustments simpler. They can also be a reliable option for tactical applications that require quick target acquisition.
• When choosing between first and second focal plane rifle scopes, consider factors like intended use (hunting vs tactical), magnification requirements, budget considerations, parallax adjustment features needed for correcting sight inaccuracies caused by errors in focus distance or windage/elevation adjustments.

Understanding Focal Planes In Rifle Scopes

A focal plane in a rifle scope is where the reticle appears and there are two types – first and second, but what sets them apart?

Definition Of Focal Plane

In the world of rifle scopes, understanding the concept of focal plane is crucial for selecting the right optic to suit your shooting needs. The focal plane refers to an imaginary plane positioned within a scope’s optical system where light rays converge and create a sharp focus on the target image.

There are two types of focal planes found in modern rifle scopes: first and second. To visualize these different placements, imagine holding a pen just outside of your eye and then farther away at arm’s length

– you’d see it change size relative to what you’re looking at because it appears smaller when placed in front (first) instead of behind (second).

Similarly, first focal plane reticles grow or shrink as magnification is adjusted; they maintain their subtension allowing for accurate range estimation across all power settings.

Differences Between First And Second Focal Plane Scopes

When it comes to choosing the right rifle scope for your needs, understanding the differences between first and second focal plane scopes is crucial. The focal plane refers to where the reticle or crosshairs are located in relation to the erector system within the scope.

First focal plane scopes are often favored by long-range shooters and military snipers because they allow for precise holdovers at any magnification setting.

However, they tend to be more expensive than second focal planes and can have variable size reticles that some hunters may find distracting.

When deciding which type of rifle scope is best suited for your needs – whether it’s precision shooting or hunting – consider factors like your intended use (tactical vs hunting), magnification requirements, budget considerations, and how you plan on using your optic (parallax adjustment, sighting in distance).

Advantages And Disadvantages Of First And Second Focal Plane Scopes

First Focal Plane Scopes provide a variable size reticle that helps precision shooting while Second Focal Plane Scopes have static reticles, making them ideal for hunting.

Pros And Cons Of First Focal Plane Scopes

When it comes to choosing a rifle scope, it’s crucial to understand the pros and cons of first focal plane scopes to make an informed decision.

Understanding the advantages and disadvantages of first focal plane scopes will help you determine if they are the right choice for your specific shooting needs and preferences.

Pros And Cons Of Second Focal Plane Scopes

Second focal plane scopes are a popular choice for hunters and precision shooters who require quick target acquisition at varying distances. One of the main advantages of these scopes is that the reticle remains in the same size relative to the target, regardless of magnification.

This makes it easier to make quick shots without having to adjust or estimate holdovers.

However, a downside of second focal plane scopes is that they may not be as precise for long-range shooting compared to first focal plane scopes.

Additionally, because the reticle size does not change with magnification, it can sometimes become too small or large depending on lighting conditions and distance from the shooter’s eye. 

Despite these drawbacks, second focal plane scopes are still a reliable option for those looking for an affordable optic with versatile use cases in hunting and tactical applications alike.

Choosing The Right Focal Plane Scope For Your Needs

Consider your shooting needs when selecting a focal plane scope, including factors such as long-range shooting, hunting, tactical applications, magnification requirements, and budget considerations.

Long-range Shooting

If you’re someone who enjoys precision shooting at long distances, then choosing the right focal plane scope is essential. A second focal plane scope is often a better choice for long-range shooting because it allows you to zoom in and out without changing the size of your reticle.

This means your crosshairs will remain the same size relative to your target, making it easier to aim accurately at longer ranges. Additionally, a larger first-plane reticle can obstruct smaller targets when viewed from afar.

Hunting

When it comes to hunting, choosing the right focal plane scope is crucial. First focal plane scopes are better for precision shooting at varying distances, making them ideal for hunters who need to quickly adjust their aim in different situations.

It’s important to also consider factors like parallax, sighting in your scope, and windage and elevation adjustments when selecting a hunting optic.

Some popular options include Vortex Optics Crossfire II Second Focal Plane Riflescopes and Leupold VX-Freedom 3-9x40mm Rifle Scope with Duplex Reticle.

Tactical Applications

For those interested in tactical shooting, the type of focal plane scope can make all the difference. Second focal plane scopes are often preferred for this application as they allow for quick target acquisition and easy adjustment for windage and elevation on the go.

Additionally, second focal plane reticles maintain their size at any magnification level, ensuring consistent accuracy even when changing zoom levels.

A prime example of a tactical optic that utilizes a second focal plane scope is the military sniper rifle, where precision shooting is paramount.

Magnification Requirements

When choosing a rifle scope, it’s important to consider the magnification requirements for your shooting needs. Long-range shooting typically requires higher magnification levels, whereas hunting and tactical applications may not require as much.

It’s also important to note that the higher the magnification, the more difficult it can be to stay on target due to parallax issues. This is where an adjustable objective or side-focus feature becomes necessary to correct any sighting inaccuracy caused by errors in focus distance and windage/elevation adjustments.

Budget Considerations

When considering which focal plane scope to purchase, budget is an important consideration. First focal plane scopes tend to be more expensive than second focal plane scopes due to their more complex construction and added features.

However, if you are looking for precision shooting at longer ranges or tactical applications, investing in a first focal plane scope may be worth the extra cost.

Hunting and general long-range shooting may not require such high-end optics, making a second focal plane scope a more affordable option that still provides accurate and reliable performance.

Conclusion: Making The Right Choice For Your Shooting Needs

In conclusion, choosing the right focal plane scope for your needs depends on several factors such as shooting long-range, hunting or tactical applications, and budget considerations.

First focal plane scopes offer a variable size reticle that changes with magnifications while second focal plane scopes provide a static reticle.

Both have their advantages and disadvantages depending on how you plan to use it.
