Glass Clarity & Reticle
The Tango-MSR’s glass quality stands out immediately, particularly at 1x where edge-to-edge clarity surpasses most competitors. During dawn shooting sessions, I could clearly distinguish targets at 150 yards even in heavy overcast. The illuminated BDC reticle proves its worth in shadowy timber, though I found myself rarely pushing past level 6 of 11 brightness settings to maintain a crisp sight picture.
Color rendition remains natural throughout the magnification range, though I noticed slight chromatic aberration when targeting dark objects against bright sky. The highly effective anti-reflective coatings minimize glare, a particular benefit when hunting in patchy sunlight through forest canopy.
Magnification & Parallax
The 1-6x range proves ideal for most .45-70 applications. At 1x, the scope functions like a red dot, allowing rapid target acquisition within brush-hunting distances. The throw lever makes magnification changes intuitive, though initial stiffness required break-in. The fixed 100-yard parallax works well for typical shooting distances, though careful head position becomes important for precision shots beyond 150 yards.
Elevation & Windage Knobs
The 0.5 MOA click adjustments strike a good balance between precision and practicality for the .45-70’s trajectory. Turret feel is positive without being overly stiff, though the clicks could be more tactile when wearing gloves. The zero-reset function works smoothly, but I found myself rarely using it given the cartridge’s typical hunting ranges.
Eye Relief & Eye Box
The 3.93-3.74″ eye relief proves adequate with .45-70 recoil, though consistent head placement becomes crucial with heavy loads. The eye box at 1x shows impressive forgiveness, allowing quick target acquisition even from awkward positions. At 6x, the eye box tightens considerably, requiring more precise cheek weld for optimal clarity.
Durability
Despite the .45-70’s substantial recoil, the Tango-MSR maintained zero through extensive testing. Initially zeroed with 325-grain loads, the scope held point of impact even when switching to lighter 250-grain rounds. The robust 30mm tube and quality internal construction show their worth here, though the added weight (18.5 ounces) is noticeable on longer hikes.

How to Choose the Best Scope for .45-70
Selecting an optic for a .45-70 rifle requires understanding both the cartridge’s characteristics and your intended use. This classic round’s substantial recoil, rainbow-like trajectory, and typically close-range applications create specific demands that not every scope can handle effectively.
Understanding .45-70’s Unique Requirements
The .45-70’s recoil characteristics set it apart from many modern cartridges. This substantial recoil impulse can wreak havoc on scopes not designed for such punishment. Internal components must withstand repeated shock while maintaining zero and mechanical integrity. Additionally, most .45-70 rifles, particularly lever actions, come with traditional mounting systems that can influence scope selection.
Magnification and Optical Quality
When selecting magnification range, consider the .45-70’s typical applications. Most hunting scenarios occur within 150 yards, where lower magnification proves more beneficial for quick target acquisition. Variable power scopes in the 1-4x, 1-6x, or 2-7x range typically offer ideal versatility. While higher magnification options exist, they often prove unnecessary and can even be detrimental, adding weight and complexity without practical benefit.
Glass quality and coatings play a crucial role, particularly during dawn and dusk hunting hours. Look for fully multi-coated lenses that maximize light transmission while minimizing glare. Consider objective lens size carefully – while larger objectives gather more light, they also require higher mounting, which can affect proper cheek weld.
Construction and Durability
Durability should be a primary consideration when selecting a .45-70 scope. The scope’s construction must withstand not just recoil, but also the rigors of field use. One-piece main tubes, whether 1-inch or 30mm, generally offer better structural integrity. Weather resistance becomes particularly important as many .45-70 rifles see use in challenging conditions. Look for scopes with proven waterproofing and fog-proofing through nitrogen or argon purging.
Mounting and Eye Relief
Proper mounting proves crucial with .45-70 rifles, particularly regarding eye relief. The scope’s eye relief should measure at least 3.5 inches, with 4 inches or more being ideal for use with heavy loads. Remember that eye relief often varies across the magnification range – verify the specifications at both ends of the power range.
Mount selection requires careful consideration of the rifle’s action type and intended use. Lever actions often need specific mount heights to clear the ejection path while maintaining proper cheek weld. Quality rings, properly torqued, prove essential for maintaining zero despite heavy recoil.
Practical Considerations
The scope’s weight and dimensions can significantly impact rifle handling. Many .45-70 rifles, particularly lever actions, balance naturally for quick pointing – a heavy or bulky scope can disturb this balance. Consider the rifle’s intended use: a lightweight setup proves advantageous for hunting in rough country, while a slightly heavier scope might be acceptable for more stationary shooting.
While quality optics typically command higher prices, the .45-70’s characteristics actually allow some budget-friendly options to perform admirably. Focus your budget on durability and optical clarity rather than advanced features that may prove unnecessary for typical .45-70 applications. Remember that proper mounting hardware and installation shouldn’t be compromised regardless of scope budget.
Frequently Asked Questions
What’s the ideal magnification range for a .45-70 scope?
For most .45-70 applications, a magnification range of 1-4x, 1-6x, or 2-7x proves most practical. Given the cartridge’s rainbow-like trajectory and typical hunting distances under 200 yards, higher magnifications rarely provide meaningful benefits. Lower starting magnifications help with quick target acquisition in brush country, while modest top-end magnification proves sufficient for the cartridge’s effective range.
How much eye relief do I really need?
With the .45-70’s substantial recoil, a minimum of 3.5 inches of eye relief is recommended, though 4 inches provides an extra margin of safety. This becomes particularly important when using heavy hunting loads or shooting from unconventional positions. Pay special attention to how eye relief changes across the magnification range, as it typically shortens at higher powers.
Can I use lightweight tactical scopes on a .45-70?
While modern tactical scopes might offer attractive features, they’re often not designed for the heavy recoil of the .45-70. Traditional hunting scopes with proven track records on magnum rifles typically perform better. Look for scopes specifically tested with heavy-recoiling cartridges, as they’re more likely to maintain zero and mechanical integrity.
What’s the best reticle type for .45-70 hunting?
Simple reticles like duplex or basic ballistic designs typically work best for .45-70 applications. Complex ranging reticles offer little advantage given the cartridge’s trajectory and typical hunting distances. Focus on reticles that provide quick target acquisition and adequate thickness for low-light visibility without obscuring too much of the target.
Testing Methodology and Disclosure
Each scope in this roundup underwent thorough testing specific to .45-70 applications. Testing included recoil resistance evaluation using both standard and heavy loads, optical assessment in various lighting conditions, and practical field use.

Final Words
Choosing the right scope for your .45-70 requires balancing several critical factors: durability to handle substantial recoil, appropriate magnification for realistic shooting distances, and practical features that enhance field use. While modern advancements offer exciting options, traditional scope designs often prove most practical for this classic cartridge.
Remember that proper mounting and setup play crucial roles in any scope’s performance. Take time to research mounting options specific to your rifle, use quality rings torqued to proper specifications, and verify zero with your chosen loads. Whether selecting a premium option or budget-friendly alternative, focusing on core requirements rather than excessive features will typically yield better real-world results.
The .45-70’s enduring popularity stems from its versatility and proven performance. Pairing this capable cartridge with an appropriate optic enhances its strengths while maintaining the practical simplicity that makes it so effective. Focus on quality where it matters most – durability, optical clarity, and reliable performance – and your scope will serve you well in the field.
