best scope for 45-70

Even though it was originally designed in 1873, the 45-70 cartridge, and the rifles that fire it, should still be near the top of every big game hunter’s wishlist. This cartridge has lost none of the power or speed that first made it popular among hunters in the late 1800s and early 1900s. Check out the list below to gain knowledge on what scope is the best scope for 45-70 rifles and to get the most out of this hard-hitting caliber.

The stopping power of the 45-70 cartridge is one of the most impressive things about it. Capable of taking down the largest of North American game such as moose and grizzly bears, as well as many African game species, the 45-70 not only serves well as a primary hunting rifle, but it also makes for an ideal guide gun or defensive weapon when trekking through thick brush in bear country.

Understanding 45-70 Cartridge

There are several notable attributes of the 45-70 that make it an outstanding cartridge for certain shooting situations. The two main attributes are power and speed.

Power

The original 45-70 cartridge, then called the 45-70-405, used 70 grains of blackpowder to propel a 405 grain bullet at 1350 feet per second (FPS) with 1600 foot pounds of muzzle energy. Keep in mind that the original 45-70 cartridge debuted in 1873 and you can see why it quickly gained so much popularity.

Thanks to modern propellants and bullets as well as general advancements in both rifles and cartridge design, today’s 45-70 cartridges are even more impressive.

Let’s take a quick look at the stats of two different modern examples of 45-70 ammunition.

AMMO TYPEBULLET STYLEBULLET WEIGHT (GRS.)VELOCITY (FPS)MUZZLE ENERGY (FOOT POUNDS)
HSM Ammunition – Bear Lo​adRound Nose Flat Point Gas Check43018013098
Remington – High Performance RifleSemi-Jacketed Hollow Point30019002450

As you can see from the table above, modern day 45-70 loads are very powerful. North American big game hunters can ethically take down any size game with these loads. From the biggest bull moose to the meanest wild hog to the gnarliest grizzly bear, the 45-70 cartridge has the stopping power to get the job done.

Speed

While the 45-70 is nowhere near as fast as some of the flat shooting varmint loads like the 22-250, that doesn’t mean it is slow. For the impressive amount of energy these loads carry, pushing 2000 FPS is still blazing fast. This is especially true for the ranges that this round excels at.

A 45-70 lever action rifle firing modern loads is best used for shots on game within 200 yards. Longer shots can certainly still be done relatively accurately, but those are best left to target shooters and not ethical hunters.

Range

The more limited effective range of the 45-70 might seem like a negative, but it was simply never designed as a long range hunting weapon. The main reason for this is the bullet drop that comes along with the speed of the bullets and the low ballistic coefficient carried by bullets of this size. In other words, the trajectory of the 45-70 round is very steep.

For example, the Remington round mentioned in the table above drops 33.8 inches from 200 yards to 300 yards! That is almost three feet of drop in a 100 yard span. There are just too many things that can go wrong with that type of bullet drops that ethical hunters will keep their shots at 200 yards or below.

Despite the relative range limitation, a rifle chambered in 45-70 particularly excels at two things.

Brush Gun

There may not be a better or more effective brush gun than a lever action rifle chambered in 45-70. The weight and energy of a 45-70 bullet delivers the deep penetration and devastating power required on tough game at the ranges usually encountered while hunting in heavy brush. However, the lower speed of a 45-70 load also prevents destroyed meat on thinner skinned targets such as whitetail deer.

Lever action rifles, which the 45-70 is typically used for, provide the fast follow up shots and fast target acquisition that hunting in thick brush can also sometimes require.

Guide Gun

A 45-70 rifle also makes an excellent guide gun. Its combination of stopping power, fast follow up shots, and easy handling allow for accurate shots when a dangerous situation arises.

A guide gun is a firearm intended to stop dangerous game at close ranges if the need arises while on a hunt. Typically carried by a hunting guide, a guide gun is usually of a large caliber, equipped with open sights or red dot sights, has short barrel length, and is easy to handle.

The use of a 45-70 rifle, such as a 45-70 Marlin lever action or a 45-70 Henry lever action, as a guide gun is very popular amongst guides in Alaska and North America. However, they also make for great guide guns in the thick brush of the African wilderness and any other locations with dangerous game in the area.

With all that being said, let’s talk about scopes for a minute before getting into the list.

Considering the best range to use the 45-70 cartridge at, you won’t need a scope with a lot of magnification. This is especially true if you plan to use it as a guide gun. In fact, a 45-70 guide gun would be better off with no magnification in order to keep target acquisition of potentially wounded or aggressive game as fast as possible. High light transmission rates and illuminated reticles are also important things to look for in a 45-70 scope. The thick brush the 45-70 excels in can give hunters more challenging lighting conditions so it is key to have a scope that can gather any light that is available.

Keep reading to help you decide on the best scope for 45-70 rifles and your specific shooting needs.

    Brian. Not for anything but a 45-70 even with Hornady’s new ammo has some much Arch mid-range is a miss. Putting a 56mm scope on lever rifle would ruin balance of rifle and get you laughed off hunt. Have owned a Henry brass sided for a few years. Sighted in at 120 yards bullet drop is more than 8” at 175 yards. Bushnell’s older Elite 4200 1.5-4x24ir. Also worked well on CZ 375 H&H hog back stock using Hornady 270gr. Moving @ 06 speeds.
    Both rifles looked the part and shot well.
