How to make unbelievable shots using handgun scopes
When you're talking optics, there's a scope application for
just about everyone. Many people are loyal to certain brands
regardless of price while others are just looking for a
great deal. No matter what your reasons, you'll have to
choose based on your shooting criteria. In other words,
you'll want to match the proper scope to whatever type of
shooting you'll be doing.
In this article, I'm going to focus on the subject of
extended eye relief and tell you why it is the most
important feature when choosing a handgun scope. A little
knowledge can go a long way before making your scope
selection.
But first, before I explain how it works, I want to give you
a brief, "general" description of what Extended Eye Relief
is. Some readers might be new to the subject, so I'll want
to get them up to speed.
Essentially, eye relief is the distance between your eye and
the rear lens (ocular lens) of the scope when the full field
of view is visible.
Now that might seem like a very simplistic definition of
what EER is, but how do you actually determine proper
extended eye relief with a full field of view?
Try this. The next time you look through a scope, move your
head around or the scope varying distances from your eye.
You'll begin to notice a black ring or shadow in your site
picture. When the black ring or shadow is completely
eliminated from your picture, your target should fill the
entire inside diameter of the eye piece and be completely
centered within the scope. Once you see that, you'll know
you have a full field of view and you'll be able to measure
the distance of eye relief.
This is critically important when choosing a handgun scope
because you'll probably be holding the scope anywhere
between 5 to 30 inches away from your eye. If you don't have
the proper full field of view at these distances, you'll
have to adjust your shooting stance in order to accommodate
the scope, something you'll want to avoid because your
shooting accuracy will more than likely suffer.
Keep in mind that your goal is to make the scope work for
you, not the other way around.
Something you should also know is that Extended Eye Relief
changes with magnification in variable power scopes.
Generally speaking, the higher the magnification the less
eye relief you have. This is important for those hunters or
competition shooters whose target sits at a significant
distance.
When higher magnification is used, the field of view narrows
sometimes making it a little more difficult to acquire the
target, especially if the target is moving. The trade off is
that even though there is less visual information for you to
process, the target is magnified by the number of times you
dialed in on the scope, making it easier to see your target
once it's in your field of view.
If, however, you're going to be hunting or shooting in areas
where your shots will be close and you're not using a rest,
then you'll need little magnification and a large field of
view. A larger field of view will always allow for quicker
target location, especially one that's difficult to see with
the unaided eye.
Just make sure that you have the proper field of view as
discussed earlier.
Some of you may be wondering what the magnification numbers
from the spec. sheet actually mean.
Let me explain. Let's say you have a scope that is 2x20mm.
The first number is the apparent magnification power where 2
means your target looks twice as large through the scope as
it does over iron sights. The last number, 20, is the
diameter of the front lens (also called the objective lens)
measured in millimeters. In general, the larger the
objective lens, the more light gathering capabilities it
carries and can therefore be used in lower light
conditions.
Because in the above example there is no other number
associated with the number 2, this tells you that this is a
fixed power scope. If it were written 2-8x28mm, then this
would be a variable power scope with 2 being the lowest
magnification and 8 being the highest magnification. Again,
the 28 represents the size of the objective lens in
millimeters.
Why are these numbers so important? Because not only will it
tell you what the magnification of the scope is but also the
diameter of the exit pupil once you know the formula.
Before I get into how to calculate the exit pupil, I'll bet
you're wondering what an exit pupil is. This may get a
little technical so please bear with me.
Here's how it works. A scope gathers light over the face of
its front or objective lens and concentrates it out into the
eyepiece in an area called the exit pupil.
The exit pupil of your scope should match the pupil size of
your eye as closely as possible (or just a little larger) to
get maximum low light performance and prevent scope
blackout. You calculate the exit pupil diameter by taking
the objective lens diameter (front lens closest to your
target) and dividing it by the scope power.
For example, a scope with a 20mm objective lens and a power
magnification of 2 will have a 10mm exit pupil. 7 to 8mm is
about the maximum size that the human pupil will dilate in
low light, so this scope will work well under low light
conditions. A smaller exit pupil would not deliver as much
light to the eye as the eye is willing to accept, however, a
large exit pupil means that the eye doesn't have to be as
precisely centered behind the scope to receive a full
image.
For adjustable power scopes, 3-9x40mm for example, you get
the exit pupil based on the power setting of the scope. For
example: 40 divided by 3 = 13.33mm exit pupil and 40 divided
by 9 = 4.44mm exit pupil. As you can see, the higher the
magnification, the smaller the exit pupil, hence the lower
the light gathering capabilities at higher magnifications.
When talking about light gathering capabilities, you'll want
your exit pupil to be the same diameter or just a little
larger than the conditions you're using the scope in. For
instance, if your eye's pupil is dilated to 5mm, and the
exit pupil of the scope is 7mm, then you have 2mm of leeway
before your eye position behind the scope becomes critical.
If the exit pupil of the scope is smaller than the diameter
of your eye's pupil, you'll start to encounter problems
seeing the full image of your target.
Just as a frame of reference, the human pupil is normally
dilated to about 5mm in standard light, 2-3mm in bright
light, and 7-8mm in low light conditions.
Whew I know my description was a little technical, but
knowing what the exit pupil is and how it works will help
you determine how to best utilize your scope.
You might also be wondering how the exit pupil calculation,
light gathering characteristics, and scope magnification tie
in with extended eye relief? Just remember, for EER handgun
scope applications you'll be holding your scope anywhere
from 5-30 inches away from your eye. This can be a
significant distance if your scope doesn't illuminate your
target well enough and the position of your eye is not
aligned with the exit pupil. These have a significant affect
on EER, making it difficult to get off an accurate shot if
not taken into account.
And speaking of accurate shots, there are a few handgun
scopes I recommend to give you the best chance of
accomplishing those shots.
I think some of the best handgun scopes for Extended Eye
Relief and light gathering capabilities are the Nikon EER
Monarch series, the Leupold FX and VX series, and the Burris
LER series. All three companies offer exceptional choices in
optics as well as full lifetime guarantees. They're rugged
and durable and 100% waterproof. They have unmatched lens
coating systems which excel in brightness, clarity, and
contrast.
Few companies are able to stack up, however, you'll have to
make the best choice for your shooting application and go
with the scope and company you feel most comfortable with.
They're not the cheapest scopes, but they're best overall
value and definitely worth the investment.
Hopefully I've clarified questions you might have had about
scope definitions and how to calculate critical components
of a scope. Now, with this information, you'll be armed with
the knowledge you need to make a wise EER scope selection.
Oh one more thing. Usually, the amount of eye relief and
magnification is listed in the specifications by most
manufacturers, so you should be able to get a good feel for
what you need after applying the knowledge you've gained
from this article.
