Hi Clay,
There's no substitute for newer technology and some of the latest new products that now have the ability to match speed and/or caliber specific information are great. I was trying to keep it simple and straight forward, but I definitely appreciate the added information, since it better rounds out the knowledge in the answer chain.
I've also recently seen some of the newest high end rifle scopes that include not only these same features, but also contain computer chip technology that will turn a reticle green when the shooter is dead on target at distances of up to a 1/4 mile away. These same scopes have built in video recording that are capable of recording up to 15 minutes of footage of the shooters kill shot.
There are some wild new innovations on the horizon, but please notice I didn't say affordable. The scope that can perform these and other functions sells for almost $5,000. and is made by a single company out of Dallas, Texas.
Sorry guys, I was getting off topic and a little ahead of myself.
Regards,
