Ultimate Guide to Choosing the Perfect Riflescope for Precision Shooting
Finding the best riflescope for long-range shooting can be a challenge. This guide will show you the importance of a good long-range scope, what exactly makes a long-range hunting scope “good,” and which riflescopes will work best with your kit. We’ll help you zero in on the best rifle scope, so you can hit your mark 100 percent of the time.
Before investing in a riflescope, there are a few things to consider, such as range and environment; type of firearm, mount, and cartridge; and your budget. With these factors in mind, you can start thinking about more features like magnification ranges, focal planes, turret options, and reticle designs.
Consider Magnification, Objective Lens, Range, and Environment
The magnification of a scope is represented by a magnification number range, followed by the diameter of the objective lens. For example, let’s break down what “3-9x40mm” means. This is a popular riflescope configuration.
The “3-9x” represents the magnification, while the “40mm” describes the diameter of the objective lens. At 3x magnification, your target will appear three times closer, whereas at 9x magnification, it will appear nine times closer. As for the best objective lens size, it really depends on your intended use in the field. One of the most common objective lens sizes is 40mm, though the larger the size, the better the image.
So which common scope range is better, 3-9x or 4-12x? The distance to your target and the environment in which you’re shooting play an important role when deciding on what level of magnification you want your riflescope to offer. You may want a different magnification range entirely.
For instance, when hunting whitetail deer in densely wooded areas of Pennsylvania, you’re probably not going to be shooting more than 100 yards (though there are many exceptions, of course).
For this application, a 3.5-10x scope such as the Vortex Diamondback 3.5-10x50 Dead-Hold BDC Riflescope, is more than sufficient.
On the other hand, for hunts within the wide open prairielands of Colorado, it's not uncommon to be taking shots that exceed 300 yards. At this range, you might want to think about a scope in the 3-18x magnification range, such as the Vortex Strike Eagle 3-18x44mm FFP EBR-7C MRAD Riflescope.
