How to Choose the Right Best Scope for 45-70

Optical clarity and lens quality

When selecting the best scope for a 45-70 rifle, optical clarity and lens quality should be your primary focus. Prioritize scopes with fully multi-coated lenses to maximize light transmission, ensuring bright, sharp images even in low light conditions. An objective lens size around 40 to 50 millimeters balances light-gathering capability with manageable size, providing clear sight pictures without adding excessive bulk.

Additionally, look for generous eye relief of at least 3.5 inches, which prevents scope eye injuries and ensures comfortable shooting. For those who value clear visibility in varied environments, a scope with premium lens coatings and ample eye relief is the optimal choice.

Durability and construction

Durability is crucial due to the heavy recoil of the 45-70 cartridge, so focus on scopes with robust construction. Opt for models with weatherproof features such as waterproof and fog-resistant seals to maintain performance in all conditions. The housing should be made from solid aircraft-grade aluminum or similar materials to withstand recoil impact without loosening zero.

A durable matte or anodized finish will reduce glare and increase longevity. For shooters seeking reliability under tough conditions, a scope offering strong recoil resistance combined with weatherproofing is the definitive selection.

Magnification and field of view

Choosing the right magnification and field of view directly impacts your effectiveness with a 45-70 cartridge. Variable magnification between 1.5x and 6x is ideal, giving versatility for close-range shots and moderate distance targets without sacrificing clarity. Fixed power scopes can work but generally limit adjustment convenience in the field.

Also, a wider field of view around 25 to 30 feet at 100 yards assists with faster target acquisition and situational awareness. Select a variable scope within this magnification range to balance precision and quick target tracking efficiently.

Reticle types and adjustments

Reticles should correspond to the ballistic characteristics of the 45-70, so prioritize duplex or ballistic drop compensated (BDC) reticles that simplify holdovers for heavy, slower bullets. High-quality turrets with precise, tactile clicks for windage and elevation adjustments allow consistent, quick zeroing after recoil. Illumination in the reticle enhances visibility in dim conditions without overwhelming daytime sight pictures.

Zero-reset or zero stop features are essential for returning to your original zero after field adjustments. Choose scopes with tactical turrets and BDC reticles for confident shot placement with this caliber.

Mounting compatibility and ease of use

Mounting compatibility is essential for stable performance and ease of use. Scopes with common tube diameters such as 30 mm provide access to a wide range of reliable mounting rings and bases. Consider mounts that allow tool-free or simplified installation methods to facilitate quick changes in the field.

Scope weight should not excessively shift the rifle’s balance; ideally, pick models under 20 ounces to maintain swift handling without fatigue. For shooters wanting straightforward setup and comfortable handling, scopes with 30 mm tubes, straightforward mounting, and balanced weight are the best match.

Which Should You Choose?

• If you’re a beginner hunter seeking straightforward use and reliable performance, choose a 3-9×40 second focal plane riflescope with a 1-inch tube for easy setup and consistent magnification.
• If you need enhanced target visibility in low light or dense cover, opt for a riflescope with a larger 50mm objective lens to maximize light transmission and clarity.
• If you prioritize variable magnification for flexible shooting distances, go for a scope offering up to 12x zoom to cover both close and extended ranges effectively.
• If you want to simplify holdover adjustments during hunting, select a riflescope featuring a Dead-Hold BDC reticle, which aids in accurate shot placement without complex range estimation.
