Second Focal Plane Scopes: Time-Tested Reliability for UK Shooters

Quick Overview

This article examines Second Focal Plane (SFP) riflescopes, the traditional choice for many UK shooters. We’ll explore their design, advantages, and applications across various shooting disciplines, helping you understand why SFP scopes continue to be a popular option in the world of shooting optics.

 

What is a Second Focal Plane Scope?

Second Focal Plane scopes have been the mainstay of riflescope technology for decades. Let’s break down their key characteristics:

• Definition: In an SFP scope, the reticle is positioned behind the magnification lenses.
• Reticle behavior: The reticle appears to stay the same size as magnification changes.
• Consistency: Reticle subtensions are true at one specific magnification (usually the highest).

The positioning of the reticle in an SFP scope means that as you adjust the magnification, the target image grows or shrinks while the reticle remains the same size. This design has been favoured by hunters and recreational shooters for its simplicity and reliability.

 

How SFP Scopes Work

Understanding the mechanics of SFP scopes can help shooters appreciate their strengths:

1. Optical design: • Multiple lenses arranged in a specific configuration • Reticle etched on glass and placed in the second focal plane
2. Light path: • Light enters through the objective lens • Passes through the magnification lenses before reaching the reticle • Only the image is magnified, not the reticle
3. User experience: • Reticle appears to stay the same size regardless of magnification • Provides a consistent sight picture across all magnification levels

This design ensures that the reticle remains easily visible at all magnifications, a feature many shooters find beneficial, especially in low-light conditions.

 

Advantages of SFP Scopes

Second Focal Plane scopes offer several benefits that have kept them popular among UK shooters:

1. Consistent reticle visibility: • Reticle remains the same size at all magnifications • Easy to see in various light conditions and at low magnifications
2. Familiarity: • Many shooters are accustomed to SFP scopes • Intuitive use for those transitioning from iron sights
3. Simplicity: • Straightforward design with fewer moving parts • Often more durable and resistant to recoil
4. Cost-effective: • Generally less expensive than comparable FFP scopes • Good performance at a lower price point
5. Wide range of options: • Available in various magnification ranges and reticle designs • Suitable for different shooting disciplines and preferences

 

Potential Drawbacks of SFP Scopes

While SFP scopes have many advantages, there are some limitations to consider:

1. Ranging and holdover consistency: • Reticle subtensions are only true at one magnification • Requires adjustment or memorization for accurate use at different magnifications
2. Limited versatility: • May be less suitable for shooters who frequently change distances • Can be challenging for long-range precision shooting
3. Reticle size at high magnifications: • Reticle can obscure small targets at high magnifications • May impact precision for some types of target shooting
4. Learning curve for advanced use: • Using holdovers and ranging features requires practice and knowledge of your specific scope

 

Applications for SFP Scopes in UK Shooting Disciplines

Second Focal Plane scopes are widely used across various shooting disciplines in the UK:

1. Hunting: • Ideal for most UK hunting scenarios • Simple and reliable in field conditions
2. Target shooting: • Popular for disciplines that use consistent distances • Suitable for club-level competitions
3. Pest control: • Effective for typical pest control distances • Clear sight picture in various light conditions
4. Recreational shooting: • User-friendly for casual shooters • Suitable for plinking and informal target practice
5. Historic and classic rifle competitions: • Often preferred for maintaining the traditional feel of classic firearms

 

Choosing an SFP Scope: Considerations for UK Shooters

When selecting an SFP scope in the UK, consider the following factors:

1. Intended use: • Match the scope’s features to your primary shooting activities • Consider factors like typical shooting distances and light conditions
2. Magnification range: • Choose a range suitable for your shooting discipline • Remember that higher magnifications may reduce field of view
3. Reticle type: • Select a reticle that complements your shooting style • Consider illuminated options for low-light use
4. Build quality: • Look for robust construction and good warranties • Consider weather resistance for UK conditions
5. Eye relief: • Ensure comfortable and safe use, especially with high-recoil firearms
6. Budget: • Quality SFP scopes are available at various price points • Balance cost with features and durability
7. Compatibility: • Check compatibility with your firearm and mounting system • Consider weight and size for balanced handling
8. Legal considerations: • Ensure compliance with UK firearms regulations • Be aware of any restrictions for specific uses or calibres

 

Maintaining Your SFP Scope

To ensure the longevity and performance of your SFP scope:

1. Regular cleaning: • Use appropriate lens cleaning tools and solutions • Keep the scope free from dirt, moisture, and fingerprints
2. Proper storage: • Store in a cool, dry place when not in use • Use lens caps to protect glass surfaces
3. Careful handling: • Avoid impacts and excessive recoil • Be mindful of the scope’s limitations
4. Periodic checks: • Verify zero regularly • Check for any signs of damage or misalignment
5. Professional servicing: • Consider professional maintenance for high-end scopes • Address any issues promptly to prevent further damage

 

Conclusion

Second Focal Plane scopes continue to be a popular choice among UK shooters for good reason. Their reliability, simplicity, and cost-effectiveness make them suitable for a wide range of shooting disciplines. While they may not offer the same level of versatility as their FFP counterparts for extreme long-range shooting, SFP scopes excel in many common shooting scenarios encountered in the UK.

Whether you’re a hunter, target shooter, or enjoy casual plinking, an SFP scope can be an excellent choice. The key is to understand your specific needs and match them with the right scope features. Remember, the best scope is the one that helps you shoot more accurately and enjoyably within your chosen discipline.

As with all shooting equipment, prioritise safety, adhere to UK firearms laws, and consider seeking hands-on experience with different SFP scopes before making a purchase. By understanding the strengths and limitations of SFP scopes, UK shooters can make informed decisions about their optics choices and enhance their shooting experiences across various disciplines.
