Factors to Consider When Buying the Best 45-70 Rifle Scopes

The more choices we have the harder it becomes for us to settle on any scope for 45-70 marlin. The fact that there is a wide variety of scopes in the market makes it is hard for most people to narrow down to which one they should buy.

Well, it doesn’t have to be hard, taking a step-by-step approach will make it not only easier but also leave you satisfied with the choice you made.

Different scopes will have different features targeted to a specific use. Today I will take you through the steps for choosing the best 45-70 lever-action rifle scopes suited for your needs.

1. What do I Need the Scope For?

best 45-70 rifle scopes

Asking yourself this question is the first and also the most important step when deciding which scope to buy. May you need a scope for hunting, hitting targets or hunting? 

Furthermore, knowing the distance from which you will be shooting will help you narrow your choices even more.

For example, if you need a gun for hunting you should decide if you doing short range hunting, medium-range hunting or long-range hunting.

This will help you establish the magnification power that you need.

You should also take the riffle that you will be using into consideration, the range of the riffle will determine the magnification that you need. 

Lastly, it is important to consider the environment in which you will be using the scope.

For your scope to perform well in adverse weather conditions it needs to be fog-proof and waterproof.

In addition, it should be strong enough to withstand harsh handling for example in the forests.

2. Consider the Magnification that You Need

best 45-70 rifle scopes

The magnification of a scope is how big the target appears.

Different scopes come with different magnifications. Some have variable magnification while others have a fixed magnification.

The magnification power of a scope will highly determine its price.

Those with a fixed magnification are usually cheaper. When buying a scope, you will see something like “3-9×40”.

This means it has a variable magnification, the target is three times large when at its lowest magnification and 9 times larger at its highest magnification.

For hunting a magnification of more than 12x is not necessary, however for long-range shooting one would need a high magnification.

There is no benefit of buying a scope with a higher magnification than that you need, in fact, it will impact negatively on your hunting experience, it will lead to inaccurate shots and wasted ammo.

If you need a scope for short-range hunting and you are on a tight budget, buying a 4x fixed scope would be a good decision. This is also to look at when looking for the best scope for elk hunting,

3. Objective Lens Diameter

Objective lens diameter is the diameter of the front lens of the scope, opposite to the eyepiece.

The objective lens diameter determines how much light enters the scope and consequently how bright the scope images are.

The lighting condition, the range you will be shooting and the magnification you will be using are key to consider when choosing a scope with the right objective lens diameter.

However, the lens size is directly parallel to the magnification levels.

For instance, with a scope labelled 3 9x40mm you will enjoy long range hunting and there will be sufficient light transmission for extreme performance.

A scope with a large objective lens diameter works best in all light conditions and high magnification range.

When shooting at low light conditions a scope with a larger lens diameter will give brighter images as it allows more light into the scope however this only makes a difference if you are shooting at a long range.

For most scopes, an objective lens of 30-40mm will give images that are bright enough in majority of the situations however for high magnification lenses an objective lens diameter of more than 50mm is more appropriate.

It is important to note that scopes with larger objective lens diameters are larger and sit much higher on the firearm when mounted and are heavier than scopes with smaller objective lens diameters.

This can make it harder to get a good shooting position, it affects the comfortable cheek and weld method and it can affect proper eye alignment with the reticle.

All this sums up to less accurate shots at close range. Larger objective lens diameter works best when shooting at higher magnification.

4. Reticle

Reticles are important in getting an accurate aiming point and can greatly improve your shooting performance.

Many advancements have been on the reticle over the years from the simple dot reticle to the more advanced mil-dot and BDC reticle (bullet drop compensator reticle).

There is an array of reticles to choose from, all having specific features targeted to a specific use, for example, the mil-dot reticle has dotted crosshairs that help to determine the distance of the target while the BDC reticle has horizontal lines on lower half which helps one to determine bullet drop at various distances to the target.

 For someone who is not well experienced with reticles, it is wise to go with the simple duplex reticle since the more advanced ones may be quite challenging to get used to.

Some reticles are illuminated while others are not, the illuminated give good performance even in low light conditions.

5. Adjustments

The windage and elevation adjustments turrets use two main adjustments systems, namely the MOA (minute of angle) and MRAD (miliradian).

1 MOA corresponds to 1 inch when shooting at 100 yards. 1 MRAD is roughly 3.6 inches at 100 yards. MRAD performs better than MOA at long distances but they are more expensive, heavy, and difficult use.

This system uses either micro friction adjustments or click adjustments. Generally, the click adjustments are more convenient to use.

The MOA per click also something to keep in mind since the smaller it is the finer the adjustments will be. 1/4 MOA per click is good to go with.

6. Eye relief

best 45-70 rifle scopes

Eye relief is how far your eye needs to be from the fast focus eyepiece in order to see the full field of view without any blockage.

A long eye relief is desirable to keep your brows safe especially when using firearms with heavy recoil.

Eye relief decreases as the magnification times of the scope increases.

Most hunting scopes have an eye relief of 4 inches or more while many scout scopes have a longer eye relief of 9 inches however they have lower magnification. 

The 45 70 cartridges are quite heavy and when you release the trigger, keeping up with the recoil might be a challenge.

Therefore, you will require to ensure that your scope has reliable eye relief to protect you against black eyes and other possible injuries.

7. Lens Coating

best 45-70 rifle scopes

Lens coating reduces glare and loss of light due to reflection hence leading to better light transmission. This results in brighter and clearer images. There are different lens coating in the market, namely:

 Coated – at least one lens has at least one-layer coating

 Fully coated – a single coating on all air-to-glass surfaces

Multicoated – multiple layers on at least one surface.

Fully multicoated – multiple layers on all air-to-glass surfaces.

The type of coating will highly determine the price. It is wise to go for the fully multicoated ones if they are within your budget. It is also good to learn how to clean the scope lens.

8. Parallax

best 45-70 rifle scopes

Scope parallax is the inconsistency one sees when they look at a fixed scope at different positions.

Some scopes are parallax-free at a certain distance while others are not, however they have parallax adjustment knobs. Scope parallax will lead to inaccurate shots and wasted rounds. 

The more features a scope has the higher its price will be.

To get value for your money you should go for ones with what you need, nothing more, to avoid spending more on features that you might never need.

Lastly, before buying a scope you should make sure it can be mounted on your firearm.

9. Price Range

The affordability of a product is critical before making any purchase.

Ensuring that you can comfortably pay for a particular product without straining your account is every customer’s desire.

However, when it comes to purchasing riflescopes, affordability is beyond what you see.

You will require to check on the quality of the item and compare it with the price.

However, it is essential to note that most products today are highly-priced not because they are of the best quality but rather the brand.

Let the price not deter you from getting the high quality you need.

Therefore, you will need to ensure that the price and the scope of quality meet your expectations when you are purchasing. This way, you will be guaranteed that your investment is not in vain.

Another factor to consider when it comes to prices is the scope’s response to different weather conditions.

Highly-priced scopes should allow you the convenience of use even under harsh conditions. The more you pay should also reflect on the performance of the item.

10. Ease of Mounting

If you are buying a 45 70 scope for the first time, then you need to consider mounting options for your device.

Mounting scopes on rifles is both easy and difficult, depending on your experiences and mounting style.

For instance, if your scope of choice does not come with mounting rings, you will require to know where you can find them. Look for the one you can get the best moa per click.

This will help hunt that big game. This is especially when determining the range shooting for ones in a close range.

Whether you are an all-time hunter or seasonal, getting to know that you can mount your scope faster brings a rewarding satisfaction.

You also need to know whether the scope will be secure if you mount and sight it in advance before the actual hunting period.

If you cannot mount by yourself, especially if it’s the first time, you also need to know what other options you have.

Only buy when you are guaranteed to find someone who will assist you in mounting. If there are other hunters within your area, find whether they can assist you first.

If not, ask for recommendations and get someone who will assist you and train you.

Ease of Where to Shop for the Best 45 70 Scopes

Frequently Asked Questions

1. What is a 45-70 rifle?

This is a .45 size firearm cartridge reinforced by 70-grain powder. Its initial label was .45-70-450, which meant the 450 grains bullet and 70 grains of powder load; this was before it was named .45-70. Its popularity has increased among the US sports hunters thanks to its perfect stopping power. You can successfully use this rifle for hunting for the big game animals, including the great bears. It has widely been used to hunt the ‘African Big Six’ and the small animals, including birds. However, this rifle is not suitable for long-range shooting; it excels at short-range shooting. .45-70 has over 150 years of history.

2. What is the range of a 45-70 rifle?

It is very effective when shooting a range of about 150 yards with the least bullet drop. It can still deliver shooting accuracy on a range beyond 150 yards but turn out to be ineffective if it goes beyond 200 yards. For instance, if you use a .45-70 load to shoot 350 to 400 yards range, the bullet will drop to about 50 inches. Such a drop can significantly affect your shooting accuracy.

Because of these inefficiencies, do not use the .45-70 in ranges that are more than 200 yards. If you are familiar with windage and elevations, you can conveniently shoot long ranges with this rifle.

3. Is a 45-70 rifle too big for deer hunting?

No. You can use a 45-70 rifle to shoot for your deer hunting trip and make accurate shots if you have the shooting skill. However, you need to know where to shoot the deer to avoid damaging the meat. If possible, always try to go for the back of the deer’s shoulder whenever you are shooting one. And this will not cause tracking of the animal. Shooting through the shoulder can spoil the meat found in both shoulders.

Whether you are walking or on your horseback, the 45-70 rifle is easy to carry and flexible to mount and fire when you spot your target. You won’t have a hard time shooting when you spot a deer.

5. How to site 45-70 rifle?

You first need to ensure that your rifle is bore-sighted. Prepare your rifle and a stable front and rear rest for optimal stability, your ammunition, eye, and ear protection too.

Focus your riflescope by concentrating your reticle and the magnification power to your paper target. When adjusting the parallax, ensure your target is crisp and clean and the reticle isn’t wandering. Make about three shots to see how far or close your shots land on the target paper.
