could use some help with reticals
Try a websearch with the spelling "reticle" instead of "retical".

Reticle - Wikipedia, the free encyclopedia
The subject can be far more complex than it might seem at first. The physioligy of the human eye and psychology of the human brain play a part. If you can't see the reticle it's useless. If you can't understand the reticle it's useless. Besides assisting in aiming various reticles can aid in measuring distance, target velocity, target size, inclination, and cant.
The common crosshair is used to rapidly locate the center of the field and assist in controlling canting of the firearm. The most complex reticles are the mil-grid type as found in scopes made by Horus Vision and a few others. They look very busy but they are just a simple uniform grid.

They offer the precision of target knobs combined with the speed of not having to twiddle knobs and count clicks. It still requires ballistic tables or a computer.
Some bullet/velocity atmosphere specific reticles are even faster to use. These compensate for drop in specific firearms. Range and wind are still estimations. Thes have the ballistic characteristics of a specific bullet at a specific velocity etched into the glass.

There are even software reticles where what is viewed though the scope can be re-programmed to anyting you want. an example is the Elcan Digital Hunter

Which to choose is far more dependent on your shooting style than on what brand or style is "best".
No reticle eliminates the need to understand ballistics, partiularly the skill of esitimating wind deflection. Some reticles do help in compensating for wind deflection , target lead, and ballistic drop. None presently available do it for you.
