Understanding What Matters in Scope Selection for the Forty-Five Seventy
Choosing a scope isn’t a one-size-fits-all proposition. The specific features and characteristics you need will depend on your intended use, the type of rifle you have, and your personal preferences. However, some aspects are particularly important when selecting a scope for a hard-hitting round like the 45-70. You’re dealing with significant recoil, and the range at which you are likely to shoot will determine the magnification you require. Let’s delve into the essential factors:
Magnification and Its Role in the Shooting Experience
The magnification power of a scope significantly impacts how well you can see your target and, ultimately, your accuracy. Lower magnification settings provide a wider field of view, which is beneficial for quick target acquisition at close to medium ranges. Conversely, higher magnifications allow you to see your target in greater detail, making precise shot placement at longer distances much easier.
For the 45-70, a versatile magnification range is usually preferable. Scopes with variable magnification, such as 2-7x, 3-9x, or even 2-10x or 3-12x, offer the flexibility to adapt to different shooting scenarios. For hunting in dense brush or timber, where shots might be taken at relatively close ranges, a lower magnification setting can provide a wider field of view. Then, if you move out onto a more open plain where the shots are longer, you can dial up the magnification. Think of it like having two scopes in one.
Objective Lens Size and the Light-Gathering Ability
The objective lens is the front lens of the scope, the one facing the target. Its size is measured in millimeters and directly impacts the amount of light that enters the scope. A larger objective lens gathers more light, which translates to a brighter and clearer image, particularly in low-light conditions such as dawn, dusk, or overcast days. This enhanced clarity is important for identifying your target.
However, a larger objective lens also means a bulkier and heavier scope. This can affect the balance of your rifle. For a 45-70, a balance is important. Objective lenses in the 32mm to 44mm range will usually provide a good balance between light gathering and a manageable profile. When selecting, take into consideration the size of your rifle and your physical size. You want something that isn’t too heavy to carry.
Deciphering Reticles: Your Guide to Aiming
The reticle, also known as the crosshairs, is the aiming point you see when looking through the scope. Different reticle types offer various features, such as holdover points for bullet drop compensation or windage adjustments. The best choice depends on your hunting or shooting style.
For the 45-70, a simple duplex reticle (thick outer lines that taper to fine crosshairs in the center) is a very effective choice for close to medium range shooting. It’s easy to see and allows for quick target acquisition.
However, as you stretch out the range, a reticle with bullet drop compensation (BDC) marks becomes very valuable. These marks, designed specifically for the ballistics of your cartridge and load, provide holdover points to compensate for the bullet’s trajectory, enabling accurate shots at various distances. Reticles with illuminated options can be helpful in low-light conditions. Make sure to find a reticle you can understand.
Eye Relief and Eye Box: Comfort and Safety
Eye relief is the distance between the scope’s eyepiece and your eye where you can see a full, clear image. The 45-70 is known for its recoil, and adequate eye relief is crucial to avoid scope bite (the unpleasant experience of the scope smacking you in the face). You’ll want to find a scope with enough eye relief to keep your brow safe.
Aim for a scope with at least 3.5 inches to 4 inches of eye relief, ideally even more. Also, consider the eye box – the range of movement where you can still see the full sight picture. A generous eye box makes it easier to quickly acquire your target, especially under pressure or in situations with limited time.
Durability and Recoil Resistance: Built to Last
The stout recoil of the 45-70 puts considerable stress on a scope. It is important that the scope is built to withstand these forces and maintain its zero. The scope should be made from high-quality materials, such as aircraft-grade aluminum, and properly sealed to be waterproof, fog-proof, and shock-resistant.
Look for scopes specifically advertised as being suitable for big-bore rifles or those that have been tested to handle the recoil of heavy-recoiling cartridges. This will ensure that your investment remains functional for years to come.
Budget and Features: Balancing Value and Performance
Scopes range widely in price. Consider how often you plan to use the rifle, and what your budget is. You can find perfectly serviceable scopes for the 45-70 without breaking the bank. It is important to note that the more you pay, the higher quality you are getting.
Features such as adjustable turrets (for windage and elevation), illuminated reticles, and advanced glass coatings can add to the cost. Determine which features are essential to your shooting needs and allocate your budget accordingly. Don’t be afraid to spend a bit more for higher quality, but don’t necessarily buy features you won’t use.
Top Scope Recommendations for Your Forty-Five Seventy
Finding the best scope for a 45-70 involves striking a balance between features, performance, and price. Here are some recommendations, categorized by price and intended use.
Entry-Level/Budget-Friendly Scopes
If you are on a budget, look at scopes with a proven track record, such as the Vortex Crossfire II. While this scope is on the affordable side, it still offers excellent clarity, a durable construction, and a great warranty. Its simple duplex reticle makes it great for general hunting. The eye relief is also good, and it’s built to handle the recoil of the 45-70. The Crossfire II is an excellent starting point that won’t disappoint.
Mid-Range Scopes
The mid-range scope category is a great place to find scopes with high-quality glass, which are typically in a lower price range, such as the Leupold VX-Freedom. They often feature illuminated reticles. Leupold’s reputation for quality and reliability is well-deserved. Leupold offers great optical clarity, rugged construction, and a variety of reticle options. They will reliably get you through hunting season, and will provide good performance for target practice. This scope offers excellent light transmission and a robust build, making it a good choice for a variety of hunting scenarios.
Premium/High-End Scopes
For those who demand the absolute best in performance, premium scopes offer unparalleled optical clarity, robust construction, and advanced features. Scopes like the Nightforce SHV series are excellent choices. Nightforce is known for its exceptional clarity, durability, and precision. The SHV line often provides options for BDC reticles, making it ideal for long-range shooting with the 45-70. These scopes offer outstanding performance at a price.
Proper Mounting: The Foundation of Accuracy
Even the best scope for a 45-70 will be useless if it is not mounted properly. Proper mounting is just as crucial as the scope itself, as it ensures stability and helps maintain zero.
You’ll need a scope mount and rings specifically designed for your 45-70 rifle. Most modern lever-action rifles utilize a Picatinny rail or a Weaver base, which provide a secure platform for mounting the scope rings. Select high-quality rings that are the appropriate diameter for your scope’s tube size (typically 1 inch or 30mm).
Be sure to follow the manufacturer’s instructions carefully when mounting the scope. Use a torque wrench to tighten the ring screws to the recommended specifications. Over-tightening can damage the scope, while under-tightening can lead to movement and loss of zero. Proper mounting is paramount.
Zeroing and Using Your Scope: Hitting Your Mark
Once your scope is mounted, the next step is zeroing, which is the process of adjusting the scope’s reticle to align with your point of impact.
Bore Sighting
Begin by bore-sighting your rifle to get the scope roughly aligned with the bore.
Target Practice
Set up a target at a known distance (usually 100 yards).
Firing Groups
Fire a small group of shots and observe where they impact.
Turret Adjustments
Use the scope’s windage and elevation turrets to adjust the reticle until it aligns with your point of impact.
Refine
Repeat the process until your shots consistently hit your desired point of aim.
Once your scope is zeroed, you can use it to engage targets at various ranges. Remember to account for bullet drop by using a BDC reticle or making adjustments to your scope. Practice at different ranges to become familiar with the ballistics of your chosen load.
Maximizing Your Rifle’s Potential
Selecting the best scope for a 45-70 is an important decision that directly affects your shooting success. By understanding the critical factors – magnification, objective lens size, reticle type, eye relief, durability, and your budget – you can narrow your choices and find an optic that perfectly complements your rifle and your shooting style. Remember to prioritize quality, eye relief, and durability to ensure years of reliable use. Choose a scope that will give you the best chance to hit your target.
