Choosing the right scope for your .45-70 is crucial for accuracy and a successful hunting or target shooting experience. The .45-70 Government cartridge is powerful, and a poorly chosen scope can't withstand the recoil or provide the necessary clarity at longer ranges. This guide will help you navigate the options and find the best scope for your .45-70 rifle.
Understanding Your Needs: Factors to Consider Before Choosing a Scope
Before diving into specific scope recommendations, let's identify the key factors that will influence your choice.
1. Intended Use: Hunting vs. Target Shooting
-
Hunting: For hunting, you'll prioritize a scope with a durable build, good low-light performance, and a magnification range suitable for your typical hunting distances. A lower magnification range (e.g., 1-4x or 2-7x) is often ideal for close-to-medium range hunting, while higher magnification might be needed for longer shots. Reticle choice is also crucial; a simple duplex or BDC (bullet drop compensating) reticle works well.
-
Target Shooting: Target shooting demands precision and clarity. You'll likely prefer a scope with higher magnification (e.g., 6-24x or higher) for pinpoint accuracy at longer ranges. A fine reticle, such as a mil-dot or MOA reticle, is essential for precise aiming adjustments. Durability is still important, but the recoil considerations might be slightly less critical than for hunting.
2. Recoil Management: Robust Construction is Essential
The .45-70 is known for its substantial recoil. A scope needs to be robust enough to withstand this recoil without damage or losing zero. Look for scopes specifically designed for high-recoil rifles, often featuring heavy-duty tubes (typically 30mm or 34mm diameter) and durable construction. Avoid cheaper scopes, as they are much more likely to be damaged by the .45-70's powerful recoil.
3. Magnification Range: Finding the Sweet Spot
The optimal magnification range depends on your intended use.
- Lower Magnification (1-4x or 2-7x): Ideal for close-to-medium range hunting where quick target acquisition is vital.
- Medium Magnification (3-9x or 4-12x): A versatile option suitable for both hunting and target shooting at moderate ranges.
- Higher Magnification (6-24x or higher): Best for long-range target shooting where precision is paramount.
4. Reticle Type: Choosing the Right Aiming Point
The reticle is the crosshairs within the scope. Several types are available:
- Duplex Reticle: A simple and widely used reticle suitable for various shooting applications.
- BDC (Bullet Drop Compensating) Reticle: Designed to compensate for bullet drop at different ranges, simplifying long-range shooting. Ensure it's calibrated for your specific .45-70 ammunition.
- Mil-Dot Reticle: Precise reticle used for precise range estimation and holdovers. Excellent for target shooting.
- MOA (Minute of Angle) Reticle: Similar to mil-dot, but uses MOA instead of milliradians for measurements.
5. Turrets: Adjustment and Repeatability
- Tactical Turrets: Offer precise adjustments and often feature zero-stop mechanisms to prevent accidental changes to your zero.
- Hunter-Style Turrets: Usually simpler and less precise than tactical turrets.
6. Illumination (Optional): Low-Light Performance
Illuminated reticles can improve visibility in low-light conditions. This can be beneficial for hunting at dawn or dusk. However, it's not strictly necessary for all applications.

Mounting Your Scope: Proper Installation is Crucial
Once you've selected your scope, proper mounting is essential to ensure accuracy and longevity. Use high-quality scope rings and bases designed for the .45-70's recoil. Improper mounting can lead to scope damage or loss of zero. Consider consulting a gunsmith if you are unsure about the installation process.
