A cartridge is a metal cylinder containing powder and a projectile. When the firing pin hits the base of the bullet, it ignites the powder and causes the bullet to fly out of the barrel.

Clicks refer to how many times the turret rotates to ensure you can see properly. Coating refers to the type of coating used on the lens. More coatings mean less glare, reflection, and a clearer, brighter, and crisper image.


Bushnell’s Dusk & dawn Brightness multi-coated formula for scope lenses. (See Coatings doa – Bushnell’s dead-on accurate ballistic reticle. These are available with yardage numbers that they range out to for more information on doa 600, dead-on accurate at 600 yards, check our review of the bone collector rifle scope dovetail – this is a design groove pattern where the base is wider than the top for mounting rings and base. This interlocking mechanism or connection design looks just like the tail of a dove.


A ballistic reticle is an illuminated crosshair that helps you aim your weapon. Ballistic reticles are useful when shooting at night or during low light conditions.

Illuminated reticles are used by hunters to see better at night. Tactical scopes use green lights to help the shooter see better during daylight hours. Longer range rifles are usually equipped with larger tubes to allow for more internal adjustment travel.


Light transmission should be realistic. For example, if you’re looking at night vision, then the number should be low because there’s less light coming into the objective bell. However, if you’re looking for daytime use, then the number should increase.

This review has good information on lens systems and how light travels. LotuTec is Zeiss’ proprietary glass protector, repellent, and anti-scratch formula. LR is Bushnell’s long-range hunting scope.


MAG-view is Vortex’s fiber-optic reference point that provides an easily seen marking for what power or magnification setting you’re on. MeoBright is Meopta’s full multi-coated lens formula that

Varminters are used by optics companies to label a specific line or series. Reticles meant for targeting small animals are called varminters. VX stands for Leupolds’ version number.


Weaver is a brand of optical equipment. A two-piece ring is best used on this mounting system. Since the cross slots are not even, you should use the correct size rings. Preventing slop is important when using this mounting system.


X96 Reticle – This reticle is an illuminated and very intuitive “tree” style ballistic reticle, designed by Burris. (See also Ballistic reticle XD Lens Elements – XD stands for Extra-low dispersion about Vortex’s glass technology to provide outstanding optical performance.)
