When you decide to shop for a new hunting scope you need to have a good idea of what you want with regards to scope specifications. You need to know the magnification, objective lens size, type of lens coating and how much field of view you require. The selection of hunting scopes available will vary depending on your needs. Tactical and Military as well as Red dot sights are all options you could consider.
No matter what kind of hunting scope you are buying, be sure to get as much as you can afford. There is no sense having an expensive hunting rifle that is not able to shoot precisely. That brings us to sighting, which is something you will need to do no matter what type of hunting scope you get. When you first get your scope, you will want to sight it in at 50 yards for precise shots, using a bore-sighter.
A Red dot sight usually has no magnification at all so in general they are rated as 1x. This will give the user the most amount of light possible as well as a wide field of view (FOV). A scope like this can have a battery life of 50,000 hours.
Many of the soldiers in the military have these red dot scopes and you may have seen them used by SWAT team snipers. The size of the dots can vary. They are also used in hunting scopes, especially for deer or turkey hunting. Many competition handguns use them too. You can vary the size of the dots by turning a dial.
Another type of scope known as the tactical scope is used on semi-automatic rifles and some of these scopes may have up to 40X magnification and 75 millimeter objective lenses and weigh several pounds. Most civilians should really not have the need for these most powerful scopes because even the military snipers usually use fixed 10X scopes most of the time.
In fixed power scopes, you may hear the term "mildot" used to describe them and this refers a unit of measurement for the angles called milliradian, which the scopes use for adjusting when range estimation is required. Fixed power hunting scopes have different specifications than variable scopes and mildot scopes can distort the field of view specifications, so they are not used when shots are under 100 yards away, such as in law enforcement situations.
Repeatable scopes will "remember" settings used when you originally adjusted the scope and will go back to that same place if you move around and shoot in different areas, without needing adjustment. Hunting scopes that aren't repeatable will need to be adjusted every time.
The adjustments of a hunting scope can be done in inch increments at 100 yards. Every click of the dial you make while adjusting the scope will move the point of impact a specific distance in the direction you are adjusting for. This is called adjusting the minute of angle or turret adjustment.
A properly adjusted hunting scope used in the proper conditions will serve any you well regardless of the price. But always remember to use the correct tool for the job and you will have many years of use and enjoyment ahead of you.
