So, you’re in the market for a new rifle scope for your .45-70 caliber rifle?

This is a buyer’s guide with features to look out for in various scopes along with reviews of four exceptional .45-70 scopes you can buy today.

The .45-70 cartridge is also known as the .45-70 Government. It was developed by the US Army for use in the Springfield Model 1873, right after the end of the American Civil War.

The .45-70 was and still is, a big hit among sports hunters in America because of it’s sheer stopping power. It can be used to put down the biggest of the big game animals, even great bears. It has been used extensively to hunt the ‘African Big Six’ as well over its 150-year history. It doesn’t mean it is good for long range shooting though, it excels at closer ranges.

It has been used to hunt everything from birds to elephants. Another impressive feature is that it does not destroy edible meat on smaller animals like deer, because of its low velocity.

Since you are in the market for a new rifle scope, we’ve compiled this best scope for 45-70 guide to make your job easier.

So, let’s begin!

Factors to Consider Before Buying a 45-70 Scope

The .45-70 has a naturally steep trajectory. This means that you’ll need to make precise distance, windage and altitude adjustments on all long-range shots.

Before you start shopping for a scope for this rifle, there are a few basic things you need to keep in mind.


The .45-70 is made for mostly close-range shooting of big game animals. So, the scope doesn’t need to have high magnification levels, but it does have to have perfect accuracy, a high range of elevation and windage adjustments with fine, small, incremental divisions per click.

You also really need to get a scope with a parallax adjuster so that you hit your mark on the first shot. You don’t want to miss and then have a buffalo or bear charge at you!

Light Transmission

Your scope should be able to produce crisp and clear images with perfect contrast from dawn to dusk. Since there’s no telling how long it will take for you to hunt your targets down, you need a lens which will produce quality images in low-light conditions.

Multicoated, anti-reflective lenses are a must because they permit maximum light transmission. A good scope will have your back if it’s dark, foggy or rainy.


Scopes don’t come cheap, and you would want an investment that serves you well for many years. Also, bushes and trees in the forest are sure to give your scope a good battering. Your .45-70 deserves a scope just as sturdy as the bullet.

Scopes made out of aluminum alloy and anodized exteriors are the best when it comes to durability. You also need lenses that will not give way to inclement weather conditions. Lenses with Nitrogen housing and O-ring seals are usually waterproof, dust and fog proof and also, shock resistant.

Eye Relief

With the amount of recoil from a .45-70, eye relief is of paramount importance. You definitely need an eye relief of at least 3.5 inches and preferably, more.

If you’re shooting from an unusual position or from a weird angle, you definitely stand a chance of the scope hitting your eyes if you don’t have sufficient buffer (eye relief.)

The Reticle

Although you won’t be shooting long range, you won’t go right up to a large and dangerous animal either. The .45-70 has quite a steep trajectory, and you need your scope to compensate for bullet drop and windage over long distances. Having holdover positions and bullet trajectory prediction systems help a lot.

The crosshairs should be clean and uncluttered, along with providing enough information. It’s also best if the crosshair is illuminated.

The 4 Best .45-70 Scopes

Now that you know what to look for in 45-70 optics, you’re all set to go out, buy one and use it the great wilderness. Here are reviews for four scopes for the .45-70 we particularly like and endorse.

What Makes This Product A Great Choice?

The 3:1 zoom ratio models are insanely popular, and it’s easy to figure out why. The scope is multi-purpose and gives you the versatility you need to tackle diverse, unpredictable hunting scenarios.

The zoom ratio erector system allows you to switch between a bigger, wider field of view and a more detailed, intricate view with one flick of the power selector.  Perfect for when you want to hit your mark with one shot.

Because of the steep parabolic trajectory of the bullet, you can compensate for wind and bullet drop with one-quarter MOA finger click adjustments.

The reticle holds zero perfectly up to 200/300 yards, and it has additional aiming points up to 500 and 600 yards. The centralized circle is ideal for getting moving targets in your crosshairs.

The multicoated optical surfaces allow for vivid light transmission, even in extremely dimly lit conditions. The glare is minimal, and the contrast is maximum, giving you a near HD, crystal clear picture. Leupold makes no compromises when it comes to optical performance.

Then, of course, there’s the durability. Aircraft-grade aluminum alloy ensures the scope can handle whatever you throw at it. O-ring seals and nitrogen purged lenses ensure that it is highly resistant to water, fog, dust, and thermal shock.
