Fixed power scopes - Minimum magnification 6x; maximum magnification 10; 8x scope recommended. What Rifle Scope Magnification Should I Get? These days, variable scopes offer wide four-, five-, and now six-times power ranges; that is, the highest magnification is four, five, or six times that of the lowest. Some new scopes have a magnification range of 8x or more. 150 yards is the maximum distance I can handle based on the previous section. Despite the fact that comparison charts are arranged systematically by magnifications like 2-7×33, often distinct manufactures have slightly unique configurations like 2-7×33, or 2-8×33. My eyesight is good, but I don't know how far out that range of magnification is useful. We want to ensure that making a return is as easy and hassle-free as possible! For example, if you know a tree is 6 feet tall, but appears to be 8 mils in your scope, the object is 750 feet away. Enjoy our FREE RETURNS. In other articles on Guns and Shooting Online we have recommended specific scopes by price class and brand name, but this is a more general treatment. Thus, a 4-inch scope can provide about 200x magnification before images become too blurry and dim, a 6-inch scope is around 300x, etc. Eye Relief The distance your eye is from the scope when you … Fixed power scopes - Minimum magnification 4x; maximum magnification 6x; 4x scope recommended. These are short range (MPBR +/- 3" typically 150-175 yards or less) CXP2 and CXP3 class game cartridges. Some have 4 or more as in a 4-12. This means that the image you see through the scope appears three times (3X) closer than it does with your naked eye. The Burris is a long-distance riflescope having a magnification of 8x and 40x. The numbers of a scope define magnification and objective lens diameter. The cartridges in this class include the .17 M2, .17 HMR, 5mm Rem, .22 LR, .22 WRF, and .22 WMR. For example: if a scope says 3×32… then the first number (‘ 3 ’) is the magnification. While there are other factors to consider when choosing a spotting scope for 1000 yards distance, magnification plays a significant role in the performance of your scope. To find the maximum useful magnification for an objective lens multiply 1000 by the numerical aperture. An adjustable objective (AO) or side focus scope adjustable for parallax is recommended. Mag, .470 NE and similar cartridges. Is 33X of magnification good for a scope? This magnification is not so powerful and is the best for viewing objects that are at a close distance to you. More magnification just makes me FEEL as though I can be more precise when the size of the group can really mess with your head. Why High Magnification Is Not Always Better Contrary to popular belief (especially by new astronomers), high magnification is not always better and there are several reasons for this. Two important numbers are given with scopes. Fixed power scopes - Minimum magnification 1x; maximum magnification 2.5x; 2.5x scope recommended. Included in this category are most of the "all-around" big game cartridges. Consequently, if you have a scope with a focal length of 1000 mm and an aperture diameter of 100 mm, then its maximum magnification is around 200x. This can be done for a wide range of target sizes if desired. Variable power scopes - Minimum magnification 1.5x to 2.5x; maximum magnification 4x to 8x; 2-7x (approximate) scope recommended. Fixed magnification 2x-3x scopes should be provided with a 20mm objective, which allows a straight 25mm external tube diameter for optimum mounting versatility and rifle balance. I've always used 7x zoom. Variable power scopes - Minimum magnification 1x to 2x; maximum magnification 3x to 5x; 1-4x (approximate) scope recommended. Basically the magnification number determines how many times better you will see an object than with your naked eye. As a 308 scope, the Athlon Optics is a powerful scope, and it comes in various magnification ranges. Variable power scopes - Minimum magnification 4x to 8x; maximum magnification 12x to 25x; 6-18x (approximate) scope recommended. When we view an object that is closer, our eyes act as a zoom and change the focal length to about 22mm. The sharpest image I have in any scope (more than two dozen from 1x to 6-24x50) from many different companies is a 2-7x36mm Kahles Helia CL. Field of View: Describes the distance measured on the ground that you can see through the scope, as in from side to side. Alternatively, a scope magnification distance chart may be expressed as a table that correlates three values – the apparent size of the target, the actual size of the target, and the distance to the target. The reticle on an FFP scope is fairly small on the lower power ranges, and then it gets larger as the scope magnification is adjusted upwards. ; Objective lens size: the larger the lens the more light it lets in to provide you a brighter image, however, weight and size will increase with larger objective lenses. Since there is a hyphen between these two numbers, it means that the magnification can range from 20 to 60. Zeroing a scope is a vital step on the road to accurate shooting – but, as Mike Morton explains, so is knowing where to aim at a host of different distances… It’s the sighting system that you must adjust to ensure that the point of aim and the point of impact coincide at your chosen distance In the model name "4 X 32," the number four refers to the magnification power of the scope. In an adjustable magnification scope such as that, the magnification can be set anywhere from three power all the way up to nine power. Close focus: the closest distance you can still see clear images, useful for birding. The whole point to this little missive is to help less experienced shooters choose a riflescope that is appropriate for the caliber and purpose of their rifle. As for example, a specification 9×54 explains that the scope has the magnification of 9x and 54mm is the diameter of its objective lens. However budget, accuracy, weight, quality of optics and durability will be crucial considerations as will be the ability to calibrate or usability of the scope. If you have the budget for a medium to high end variable, then there is no reason not to purchase a scope in the 4x-16x range. A magnification of range 18 x to 25x is preferable when looking for the best scope magnification for 1000 yards. Appropriate scopes offer a reasonable field of view at low power and enough magnification for long range shots at big game animals when they cannot be avoided. So, instead of the 3-9x that once awed sportsmen … 33X is a good value for the magnification of the eyepiece. Several formulas are used to determine magnification from the optical power in diopters, but the most common are only two: M = D × 0.25. What do rifle scope numbers mean? For instance, a telescope with an 80-mm-wide lens and a 400-mm focal length has a focal ratio of f/5. Scope Focal Ratio (f/number): A lens or mirror’s focal length divided by its aperture. A rifle scope is recognized by the magnification or the power and diameter of its objective lens. When shooting targets at 400 yards, they will appear to be 100 yards away through a scope with 4x magnification. If we wanted more magnification, we could use an eyepiece with a shorter focal length, such as 10mm: 1200mm/10mm = 120x magnification. It is generally recommended to shoot dangerous game at ranges between 50 and 150 yards whenever possible, so high magnification scopes are not necessary. And here is how to compare rifle scopes. Scope magnification is a multiplication measurement compared to the average naked eye. Mag., .460 Wby. You will find two numbers mentioned on the scope. As the magnification increases, the apparent distance to the image decreases in direct proportion. You need to use an eyepiece with a focal length of 5 millimeters to acheive the 200X magnification. scope. You can even print a chart that shows the distance for each circle at each magnification that is present on the scopes magnification ring. The chart below will give you a matrix of the range of useful magnifications for each objective lens and eyepiece lens magnification combination. For example, a 4X32 scope has a four power magnification which means you can see 4 times better than you could without the scope. Higher power is very hard to use. Now, had the target been a LOT smaller, perhaps I would have increased the magnification. Mark your magnification ring at this point to align with the indicator mark on the tube body. Scopes also come in a variable or adjustable power that offers a range of magnification. I've also been window scope shopping, and want to make sure I'm getting what I … For a fixed 4x scope or a 2-7x zoom, a 32mm objective lens is more than adequate. Examples include the .357 Mag., .38-55, .44-40, .44 Rem. A 6X42 scope has a six power magnification and an … Several formulas are used to determine magnification from the optical power in diopters, but the most common are only two: M = D × 0.25. For each category there are examples of suitable calibers. Examples of such cartridges are the .17 HMR, .218 Bee, .22 WMR, .22 Hornet, .256 Win. When looking at Mil Dots through a scope, one Mil is the distance from the center of one dot, to the center of the next dot (not the space between the dots). Fixed power scopes - Minimum magnification 3x; Maximum magnification 6x; 4x scope recommended. You would describe this scope as a "three to nine by forty." As for example, a specification 9×54 explains that the scope has the magnification of 9x and 54mm is the diameter of its objective lens. It’s usually the first number (or range of numbers) on a scope. Generally, magnification of the scope is important while comparing rifle scopes. The forty (40) is the objective lens diameter in millimeters. THE MICROSCOPE DEPOT © 2020 - TERMS & CONDITIONS All Rights Reserved: Toll Free: 1-888-726-7378 CONTACT US ; Field of view (FOV): this is how much you can see at a certain distance out at a certain magnification level. It really depends on your needs, but we’ll get into talking about that later. For example, back then I use to know a few guys who shot a .22 based match with smaller metallic targets at ranges of 50 yards out to 100 yards for a score based on hits and time. These are CXP2 and CXP3 class game cartridges with a MPBR +/- 3" typically between 250-300+ yards. Copyright © All rights reserved. At a certain point, all more magnification does is increase mirage. The magnification of the scope depends on the focal lengths of these two lenses. While there are other factors to consider when choosing a spotting scope for 1000 yards distance, magnification plays a significant role in the performance of your scope. When all you're doing is listening for the "ding" and the size of the group doesn't matter, I feel very comfortable with the 10X. The 9 means nine power, or nine times (9X) closer than it appears with your naked eye. The second number is the total diameter of scope’s objective lens. 2. The first number indicates the magnification power of the scope and the second number gives the diameter of the objective lens (the lens at the far end of the scope). A telescopic sight, commonly called a scope, is an optical sighting device based on a refracting telescope. I have my own ideas, I just want to see what everyone else is doing to compare. 2. Users require reticles which have spaced dots or hash marks along the vertical and the horizontal axis. 4 The eyepiece’s focal length (for example, 25mm) To find the magnification, we’ll simply divide the numbers: 1200mm / 25mm = 48x magnification That’s it! These rimfire and small centerfire cartridges are useful for shooting varmints such as groundhogs and prairie dogs (CXP1 game) at maximum ranges between about 125 and 200 yards, depending on the specific caliber. Typical maximum ranges run 225-300 yards. M = D × 0.25 + 1. where M is the magnification, D is the optical power in diopters and 0.25 is the reference distance in meters. I've always used 7x zoom. Thus, doubling the magnification from 3× to 6× will cause the target’s image to appear half as far away. Once again, this is more tricky than it might sound, because you can’t trust the “18” mark on the magnification … The first number is the magnification of the scope while. This includes 4-14x and my personal favorite, the 6-24x. The telescope’s focal length (for example, 1200mm) 2. Scopes for short range big game cartridges. Fixed power scopes - Minimum magnification 6x; maximum magnification 12x; 10x scope recommended. Thus, a 4-inch scope can provide about 200x magnification before images become too blurry and dim, a 6-inch scope is around 300x, etc. A scope with great glass may permit more detail in the image than a much higher magnification with lesser quality glass. For example a 2-7x33 scope might have a 51’ field of view on 2x but only a 17’ field of view on 7x magnification. When we look at an object which is an infinite distance away (e.g. If we look at something on the horizon a long way off, we see lots of things around that object i.e. Mag. we have a larger fiel… If you know two of these values, this table will tell you the third value. This is a variable scope because you can vary the magnification of the scope from three to nine, stopping anywhere in between. That's the end opposite the end you look through. The second number – 60, represents the maximum magnification that you can get with the scope. I've been spoiled by them. The magnification of a spotting scope is designed for viewing at ad distance where conventional binoculars no longer function. Or distances in between those? 2. 1. Now, back then, there were some higher-powered scope models available, but they were really considered a “specialty” rifle scope and commanded a high price. Scopes for short to medium range varmint cartridges. For example, if your rifle is a .250 Savage (which is not listed below), you can reasonably use the scopes recommended for the .257 Roberts. You will find two numbers mentioned on the scope. Variable power scopes - Minimum magnification 2x to 3x; maximum magnification 7x to 9x; 3-9x (approximate) scope recommended. A quick video to talk about scope magnification. So, let’s take this one: Copyright 2007, 2013 by Chuck Hawks. The first number is the magnification of the scope while; The second number is the total diameter of scope’s objective lens. Identify the numbers describing the scope. To be honest, the Nightforce 2.5-10X32 is my favorite scope of all that I've owned. Not only will you have the ability to better identify your target at greater ranges, but you will also retain an acceptable field of view for closer targets and movers. Shop now and get Free Value Shipping on most orders over $49 to the contiguous 48 states, DC and to all U.S. Military APO/FPO/DPO addresses.. Magnification is typically the first number that you see in scope performance. Basically the magnification number determines how many times better you will see an object than with your naked eye. the stars), the focal length, or the distance from the cornea to the retina, of a normal relaxed eye is about 1.7 cm (17 mm). This allows you to compare certain aspects of a 6-24x scope with a 3-18x scope. If we wanted more magnification, we could use an eyepiece with a shorter focal length, such as 10mm: 1200mm/10mm = 120x magnification We could also use these eyepieces with a … Why High Magnification Is Not Always Better . The overall quality of the scope’s design including its weight, quality of the glass used and the field of view will also make the scope a masterpiece. The number followed by an "X" is the magnification. Totally depends on distance AND target size. For those new to the optics game a 2-7x33 means that the scope has a variable magnification ranging from 2x to 7x and the objective lens diameter (the scope lens closest to the muzzle) is 33mm. A scope is designed to hit targets at range such as game or enemies. Scopes for medium to long range varmint cartridges. We could also use these eyepieces with a different telescope (say, with a 600mm focal length) to get different magnifications: 600mm/25mm = 24x magnification Milling reticle. If you don’t mind the smaller reticle, or, if the smaller reticle is an issue, and you don’t mind shooting a deer on a higher magnification, then an FFP scope for deer might be a good option. These are CXP3 and CXP4 class game cartridges intended for hunting large predators (the great bears and big cats), bovines, rhino, and elephant. On a variable scope the field of view will be greatest on the lowest power and smallest at the highest power. M = D × 0.25 + 1. where M is the magnification, D is the optical power in diopters and 0.25 is the reference distance in meters.
