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.

It also includes a QTA or quick target acquisition eyepiece, allowing you to use the scope for snapping in to your target even if it’s on the move or is relatively small.

Frequently Asked Questions

Is 45-70 worth it?

Although the .45-70 is a highly accurate cartridge, it is difficult to shoot at extended distances due to the bullet’s moderate velocity and poor ballistic coefficient, which combine to generate a fairly steep trajectory. Between 350 and 400 yards, a bullet dropped nearly 50 inches with a.45-70 load.

What is the .45-70?

The 45-70 rifle cartridge, commonly known as the.45-70 Government, was created at the United States Army’s Springfield Armory for use in the Springfield Model 1873, dubbed the “Trapdoor Springfield.” by collectors. The new cartridge replaced the stop-gap 50-70 Government cartridge, which was introduced one year after the American Civil War ended in 1866.

What is the accuracy for the .45-70?

The 45-70 Springfield’s minimum acceptable accuracy was about 4 inches (100 mm) at 100 yards (91 m), but the heavy, slow-moving bullet had a “rainbow” trajectory, dropping several yards (meters) at ranges more than a few hundred yards (meters). A experienced shooter could reliably strike targets measuring 6 6 feet (1.8 m) at 600 yards (550 m) while firing at a known range. Because precision targeted fire on a man-sized target was only effective to around 200–300 yards (180–270 m), it was mostly useful in mass or volley fire.

What was the predecessor to the .45-70?

The .50-70-450. 

The .50-70-450 cartridge was adopted in 1866 and used in a variety of rifles until 1873, many of which were percussion rifled muskets converted to trapdoor action breechloaders. 

The trapdoor breechblock was milled out of the back of the barrel, and a.50 caliber “liner” barrel was installed inside the.58 caliber barrel. The .50-70 bullet was popular among hunters because it was larger than the .44 caliber and hit harder (see terminal ballistics), but the military concluded in 1866 that a .45 caliber bullet would provide better range, penetration, and accuracy. Despite this, the .50-70 was adopted as a stopgap measure until a better rifle and cartridge could be created.

Was the .45-70 successful with hunters?

The .45-70 was an instant hit among sportsmen, as is typical of military ammunition, and the .45-70 is still in use today. The conventional 405-grain load is now considered suitable for any North American big game within its range constraints, including great bears, and due to the bullet’s low velocity, it does not ruin edible meat on smaller animals such as deer. It’s ideal for big-game hunting in bush or thickets, where range is normally limited. 

The .45-70 has been used to hunt the African “big-five.” when loaded with the right rounds at the right velocities. The .45-70 cartridge has been loaded and used to hunt everything from birds to elephants, and new development work is still ongoing.

Is the 45-70 obsolete?

The .45-70 isn’t an out-of-production cartridge. “obsolete” or “no longer in general use” is what “no longer produced or practiced” signifies. The .45-70 is not obsolete because many shooters still use it. They’re still being made, they’re still in widespread usage, and they’re still effective.
