Bushnell Hunting Rifle Scopes

Bushnell Hunting Rifle Scopes

Bushnell Optics was founded in 1948 by David Bushnell. Since then, Bushnell Optics has offered hunters an up-close and personal view of the world. Bushnell hunting rifle scopes and binoculars are designed by hunters for hunters.

What are the differences between fixed and variable power scopes?

This can be explained by offering an example. Say, for instance, that 4-9X40 is engraved on the side of the tube. The following explains how to understand that notation:

  • Magnification: The X in the code indicates the power of magnification. A 4X means you are going to see things four times as large with the riflescope as with the naked eye.
  • Fixed power: A single number before the X, such as in 4X40, indicates a fixed-power rifle scope, where the magnification is preset at the factory and cannot be adjusted. A fixed-power scope offers a clearer, brighter view. Since there is nothing to adjust, a fixed-power scope is a simpler mechanism and has fewer parts so that less can go wrong. It is easy to use and an excellent choice for beginners.
  • Variable power: A dash between the first two number, such as "4-10X40," indicates a variable power scope, where the magnification can be adjusted. The lowest magnification, four, shows objects four times larger than with the naked eye. At the highest setting, objects become 10 times larger.
  • Objective lens diameter: The large lens at the front of the laser scope is called the objective lens. The last number of the code indicates the objective lens diameter in millimeters, between 32 millimeters and 50 millimeters. A scope labeled 3-10X40 has a 40mm objective lens.
What else should be considered when choosing a hunting rifle scope?
  • Objective lens: A large objective lens offers a trade-off. It provides a brighter, clearer sight picture but makes for a heavier scope that must be mounted higher to compensate for the larger lens.
  • Reticle: The reticle is the rifle scopes built-in aiming point and may take any number of forms: crosshairs, posts, dots, circles, scales of measure, or some combination of these.
  • Eye relief: The distance between the shooters eye and the scopes rear lens when able to view a sight picture.
  • Weight: A large, heavy scope may seem wonderful for shooting from a stand, but carrying it through miles of rough country becomes less wonderful quickly.
  • Turrets: Bushnells patented T-Lok turrets lift and turn for quick adjustments without tools. Press the turret knob back down, and the turret locks firmly into place.
  • Parallax adjustment: Hunting scopes are adjusted for 100 yards. At ranges much greater, or much less, than 100 yards, the image may waver with any movement. The adjustment for extreme long range or extreme short range accuracy is called a parallax adjustment.
