Your Mission:
Tactical Scopes
Intelligence:
if you shoot a rifle to any great degree, then you know that a scope is one of the best accessories that you can get for it. While iron sights are fine for closer shots, at long distances, a scope is almost a necessity. Scopes can be zeroed in using groups of three to five shots and a shooting rest. To do this, one keeps shooting groups and adjusting the windage and elevation until the groups are tearing holes in the target exactly where the shooter is aiming. When considering getting a scope, there are some important variables to consider. You want to weigh cost against use. It makes no sense to buy a thousand dollar scope for your plinking rifle, unless you’re practicing for the Olympics. Likewise, it makes no sense to mount a cheap Chinese plastic scope on a high performance, precision rifle. When it comes to rifle scopes, choose the right tool for the job.
It’s true that a scope can dramatically help you to shoot better. Not only does it magnify your target and provide you with a reticle to put exactly where on that target you want the bullet to hit, but it also can help those with less than perfect vision. If you adjust the ocular eyepiece, it is possible to focus the sight picture clearly and crisply.
Two of the most important aspects of scopes are power and light. The power is how much your scope magnifies your target. The light is how bright your target appears through the scope. Scope power is noted in multiples. A four power scope makes your target four times closer that it appears with the naked eye. Most common deer rifles use a 3x9 scope, which is adjustable. A 3x9 scope is low enough at 3 power to let a lot of light in for close up shots, and the 9 power is useful for targets far away. With a scope of this type, you should keep it set at 3 power, and only dial it up to 9 for distant shots. If you leave it at 9 power all the time, it won’t be useful for the those close up shots that surprise you. Try to be a realist when it comes to choosing what power your scope should be, and gauge your decision off what distances you will be shooting at 80 percent of the time. If you’re a hunter, keep in mind that most types of game are taken within 100 yards. How a rifle scope performs in low light conditions is determined by the amount of light that it delivers to your eye. This is known as the exit pupil. If you divide the objective lens size by the power f the scope, you can figure your exit pupil. Good quality rifle scopes will show an exit pupil of around 3 or 3.5 mm. Keep in mind that the higher the power on a rifle scope, the less light it will gather. In addition, there is a general rule of thumb that states that the larger the objective lens, the brighter your sight picture will be. There is a trade-off at play there however, as larger lenses will sit up higher on the rifle. As far as light is concerned, the larger the objective lens, the more light it can let in. For hunting and tactical rifle scopes, the objective lens is generally 40 mm or more. This lets plenty of light into the scope so your target is clear, and yet doesn’t make for an ungainly tube to take into the woods. Game animals are generally seen most early in the morning and late in the evening.
Lastly, you want your scope to feature sturdy, audible clicks on the windage and elevation knobs. This is so that you can adjust these variables while looking through the scope, without losing your sight picture. |
