What do rifle scope numbers mean? A target at 600 yards, used with 4x magnification, will appear to be 150 yards away. You would describe this scope … 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. A 6X42 scope has a six power magnification and an 8X32 has an eight power magnification. Items you will need. These are short range (MPBR +/- 3" typically 150-175 yards or less) CXP2 and CXP3 class game cartridges. To make it even better, the reticle is self-illuminating increasing accuracy at dusk or dawn. Objective Lens Size: The larger the objective lens size the brighter the image through the scope appears, larger lenses are heavier and can add a significant amount of weight to a 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. 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. With these scope models, there will be a range of numbers (usually going lower to higher) that are separated by a hyphen. This can be done for a wide range of target sizes if desired. Your scope is now capable of ranging 9 inch, 18 inch and 20 inch targets, depending on the magnification you have the scope set on. Appropriate scopes need a wide field of view as well as enough magnification to allow shots across ravines and clear cuts. Just remember that your most beneficial magnification setting will be the one that still gives you the clearest, best image all the way around. The benefit of the Spot On program is that it calculates the distance that each circle represents at every magnification. This includes 4-14x and my personal favorite, the 6-24x. 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. Scopes for "all around" and long range big game cartridges These are CXP2 and CXP3 class game cartridges with a MPBR +/- 3" typically between 250-300+ yards. Typical maximum ranges run 225-300 yards. Once again, this is more tricky than it might sound, because you can’t trust the “18” mark on the magnification … 4 An adjustable objective (AO) or side focus scope adjustable for parallax is recommended. That’s it! The chart below will give you a matrix of the range of useful magnifications for each objective lens and eyepiece lens magnification combination. 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. Nine to twelve power is good for long distance shooting and 20 power is great for paper targets that aren't going to move. we have a larger fiel… This magnification is not so powerful and is the best for viewing objects that are at a close distance to you. You may find that monoculars come with a specific magnification power and lens size, such as an 8 x 25, which is a monocular with an 8x magnification and a 25mm lens. The number 32 in the 4 X 32 model name refers to the diameter in millimeters of the objective lens. I have my own ideas, I just want to see what everyone else is doing to compare. I was thinking about setting up some targets at different ranges (100 yards 200 yards, 300, etc). The second number is the total diameter of scope’s objective lens. Mag., .460 Wby. I've always used 7x zoom. 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. ; Field of view (FOV): this is how much you can see at a certain distance out at a certain magnification level. Likewise, this scope with a 20mm eyepiece would bring Saturn and its rings into view. Why High Magnification Is Not Always Better . Ans. Reviewing the Nikon Monarch 7 Series of Rifle Scopes. This refers to the cone size of light emerging out from the eyepiece lens. Fixed power scopes - Minimum magnification 1x; maximum magnification 2.5x; 2.5x scope recommended. You may try out several different monoculars with a set magnification power and lens size to get a … This provides (in the case of a 2.5x20mm scope) an 8mm exit pupil (light pencil). Scopes for "all around" and long range big game cartridges. 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. Fixed power scopes - Minimum magnification 4x; maximum magnification 6x; 4x scope recommended. Mag. Several formulas are used to determine magnification from the optical power in diopters, but the most common are only two: M = D × 0.25. Magnification of the scope. This article should steer the reader in the direction of the correct magnification of either a fixed power scope or an appropriate magnification range of a variable power scope for their hunting rifle. You might believe that greater magnification is always better. Copyright 2007, 2013 by Chuck Hawks. These are often thought of as woods and brush calibers, where a wide field of view is usually more important than high magnification. The telescope’s focal length (for example, 1200mm) 2. A 4-power scope enlarges the image four times. An adjustable objective (AO) or side focus scope adjustable for parallax is recommended. Another way to ask this would be, what magnification do you need to meet the accuracy of your rifle at those distances? Most observation done with a spotting scope requires a magnification of 30x – 40x, which assures that most scopes are capable of producing reasonable images. The Burris is a long-distance riflescope having a magnification of 8x and 40x. I recently purchased a scope with a max magnification of 9x. That sounds good, but there are drawbacks to power. You can even print a chart that shows the distance for each circle at each magnification that is present on the scopes magnification ring. Examples of such cartridges include the .25-35, 7-30 Waters, 7.62x39, .30-30, .307 Win., .32 Spec., .358 Win., .35 Whelen, .350 Rem. Some new scopes have a magnification range of 8x or more. We could also use these eyepieces with a different telescope (say, with a 600mm focal length) to get different magnifications: 600mm/25mm = 24x magnification These brief caliber lists are not intended to be all-inclusive, so if your caliber is not listed, find something similar and there is your recommended scope. Variable power scopes - Minimum magnification 1.5x to 2.5x; maximum magnification 4x to 8x; 2-7x (approximate) scope recommended. 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). In a 3-9X40 scope, the 3 means three power, or 3X. The magnification of a spotting scope is designed for viewing at ad distance where conventional binoculars no longer function. Close focus: the closest distance you can still see clear images, useful for birding. For example, a 3-9X36 is very common hunting configuration. Examples include the .357 Mag., .38-55, .44-40, .44 Rem. 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. You will find two numbers mentioned on the scope. A magnification of range 18 x to 25x is preferable when looking for the best scope magnification for 1000 yards. A target viewed through a 3× magnification scope will appear to be three times closer than its actual distance – targets at 300 yards will appear as if they were 100 yards away. These are CXP2 and CXP3 class game cartridges with a MPBR +/- 3" typically between 250-300+ yards. 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. Magnification is typically the first number that you see in scope performance. It is equipped with some form of a referencing pattern (a reticle) mounted in a focally appropriate position in its optical system to give an accurate point of aim. On the other hand, sometimes I'm shooting 1/4-MOA targets @ 100-yards, and might use the full 27x. Examples of such cartridges are the .17 HMR, .218 Bee, .22 WMR, .22 Hornet, .256 Win. Variable power scopes tend to be most popular for hunting applications. Scope Aperture: The diameter of a telescope’s main lens or mirror — and the scope’s most important attribute. For example, a 4X32 scope has a four power magnification which means you can see 4 times better than you could without the scope. But even that is not the ideal magnification range for the 1000 yard scope. A rifle scope is recognized by the magnification or the power and diameter of its objective lens. The magnification of the scope depends on the focal lengths of these two lenses. Fixed power scopes - Minimum magnification 2x; maximum magnification 4x; 3x scope recommended. For example, a 4X32 scope has a four power magnification which means you can see 4 times better than you could without the scope. This allows you to compare certain aspects of a 6-24x scope with a 3-18x scope. 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! Identify the numbers describing the scope. You need to use an eyepiece with a focal length of 5 millimeters to acheive the 200X magnification. Fixed power scopes - Minimum magnification 2x; maximum magnification 4x; 2.5x scope recommended.
