Buyers’ Guide

rifle scope under 400

While looking for a good and convenient rifle scope you must be worrying about its quality and specificities. So, to make your search easy, we’ve compiled a complete buyers’ guide that will aid you in buying an incredible scope for your gun.

What features to look for in 400 dollars scope?

As we all know, hunting down animals makes the shooter happier and triumphed. And a good scope is going to help you a lot. But, before getting a scope you should look over a few following things.

  • Magnification

Magnification is an important element while buying a scope. You should look for a scope that will give you a clear image at its least and highest power. Moreover, it should provide you with an exceptional possibility of shooting the target in a short time with greater accuracy.

  • Accuracy

Accuracy is another notable feature that you must look into. Mainly, accuracy of a scope depends upon the adjustments you will make while tightening your mounts. However, accuracy increases many folds by the proper adjustment of turrets and parallax. 

This feature will help you while shooting at long distances.

  • Hunting in low light

Most animals are active during the night. That’s why most hunters love to hunt in the dusk or in the darkness of night. In this case, you can’t rely only on the moon light and certainly want a good low light rifle scope.

Such rifle scopes make use of the available light. Additionally, illuminated reticle, wider lens and a well-built design will sum up to give you a top quality rifle scope for hunting in low or no light.

Some kinds of scopes

Before buying a scope for your daily hunting and shooting, here are 3 main types of rifle scopes which you may like to consider.

  • Fixed Scope

These are rifle scopes with fixed magnification. They have certain advantages over other ones such as they are brighter and easy to use – just aim and then shoot the target. Also, they are more reliable, brighter and give a clear view.

  • Variable Scope

Variable scopes have a range of magnification that gives the user the opportunity to adjust the magnification of the lens according to his requirements. Also, such scopes are heavier than the fixed ones.

  • Night Vision Scope

No doubt, many hunters prefer hunting during the day because of the more light, but you’ll find more wildlife and pests during the night. And we agree that shooting in low or no light environments is quite challenging. So, for such situations there are night vision scopes made with tough built-ups. 

Such scopes would be great for you if you are a night time hunter.

What is the difference between a scope with an aluminum body and that made with steel?

The material of your scope is pretty important as it decides the sturdiness of the scope and whether it’ll be able to resist the heavy recoil of the firearm. 

Scopes with steel bodies are not quite common and are not preferred by the professional hunters. Whereas, the ones which are made up of aluminum tend to last longer and are more durable. Aluminum scopes are built for rough usage.

  10. Swarovski Z3 4-12×50 BT

What is the best magnification for rifle scopes?

The best magnification for rifle scopes is around 4x.

The scopes with 4x to 6x magnification power are considered to be great for hunting. Whereas, 10x is sufficient for shooting around 1000 yards – considering that the target is large enough to get a good image and not moving fast.

What magnification do I need to shoot 400 yards?

According to the rule of thumb, about 1-1.5x is enough for 100 yards. So, a 4x-6x scope would be great for 400 yards. However, you might face some problems while hunting with a 1.5x or 2x at 400 yards.

How far can you shoot with a 12x scope?

You can shoot about 1500 yards with a 12x scope.

If your shooting game is strong, then with a good gun and a 12x scope you can shoot at 1500 yards easily. However, the eye resolves about 1 MOA, so you’ll be able to see an 8″ target at 800 yards.

What is the advantage of 50mm scope?

A scope with 50mm objective lens offers a large exit pupil which will provide you with greater flexibility while looking through the scope and you can get your target in no time. Moreover, a 50mm scope would be great in low light situations due to its greater diameter.

Who makes the clearest rifle scope?

There are many brands notorious for making clear rifle scopes, but Nikon holds its reputation for manufacturing ultra-clear glass for a long time, and this is what you want the most in a rifle optic. The Nikon Buckmasters II 4-12x40mm scope offers great clarity and quality at an affordable price.

Does parallax affect accuracy?

Yes, the parallax affects accuracy. When your eye is at the edge of the exit pupil, maximum parallax occurs. There is an error at long distances even when the parallax is adjusted. However, at short ranges the parallax does not affect accuracy.

What power should you sight your scope in on?

You should sight your scope in on the highest power. Also, if you are mounting the scope, mount it while the scope is set on the highest setting.

Does changing zoom affect zero?

Zero should not be affected while adjusting the magnification. The reticle of your scope can be affected depending on whether it is FFP or SFP. FFP reticle will adjust according to the magnification while there is no such option with SFP reticle.
