Hunting for Whitetail Deer, Mule Deer, Elk, Moose, Black Bear or Coyotes you will need a ability rifle scope. The following tips may help with your selection.
First find a ability scope that fits in your budget, buy the best you can afford. You will never go wrong buying the best, but we all have budgets.
Rifle Scope
First, consider the light convention ability of the scope. To do this, look at the large end of the scope. It will be measured in millimeters. The larger the objective lens the more light it will gather. If you are hunting early morning or late evening (if your not, you should be) you need to obtain as much light as possible. A scope size will look like 9x40. That means that you will see the object 9 times magnification, and 40 would be the objective lens. Here is where you obtain light. The larger the objective lens, the more light it gathers.
Now the example above would be for a fixed magnification scope. I prefer a rifle scope that has adjustable magnification. A scope like 4-9x40 means that it is adjustable from 4 power to 9 power magnification. The scope set on 4 power will give you wider field of view (Fov). If you are shooting at a entertaining target then lower magnification is best. It will make it easier to track your entertaining target. The higher the magnification, the narrower the Fov. consider the zoom highlight on a camera, works much the same.
Next make sure the scope has manifold coated lens. This means that each lens in the rifle scope has manifold coatings which will reduce the loss of light, provides a higher disagreement image and reduces glare. There are dissimilar types of coatings used. The type of coating depends on the manufacturer.
Next, your new scope should have windage and elevation adjustments. These are the dial protrusions on the top and the side. The top adjustment should be the elevation or up and down adjustment. The windage or left to right is commonly on the right side of the scope. Each of can be convert by removing the protective cap and turning with your fingers. Each click commonly is ¼" in 100 yards. These clicks are fairly easy to hear.
The next thing to consider is the exit pupil size. That would be the end of the scope nearest your eye. Again, the larger the exit pupil size the brighter the image will be. Usually you can divide the magnification power by the objective lens to find the exit pupil size. A 4x40 would then give you a 10mm exit pupil. In other words, the size of the column of light that comes out of the exit pupil lens.
An prominent consideration for me personally is the eye relief. Eye relief means how far your eye can be from the end of the scope and still give you a full field of view (Fov). With a long eye relief you can be farther from the end of the scope. If you are too close, the rifle recoil may cause the scope to hit your eyebrow causing a nasty minute cut or at least a bruise. If you select a scope with a fairly short eye relief, make sure it has soft rubber surrounding your end of the scope. This will give a minute more protection from the recoil.
Find a scope that is sealed, waterproof and fog proof, one that is scratch resistant. Falls, going straight through brush can all scratch your scope. And by the way, if you fall or otherwise shock your scope, you should sight it in again to make sure your shot at a trophy will hit its mark.
Finally, have your scope mounted on your hunting rifle by a professional. If you buy your new scope from a ability dealer, they will mount your scope at no charge.
I won't get into the internal parts of rifle scopes. What I have written is the layman's version of choosing a new rifle scope.
My personal preference is a 3-9x40. I believe this is an perfect rifle scope for big game hunting.
