Baddad4570 - have you ever used or shot a Sheppard scope ? They are caliber & game specific w a reticle based on the sweet spot of your choice. I have heard they were even used in Vietnam and couldn't confirm it.
Ballistic reticles are almost common place now but they were one of the first. A gent said he bought a Sheppard for .22 and was hitting tin can at ridiculous ranges. In theory, the glass has done the math but the shooter still has to dope the wind & range conditions.
Laser range finders have taken some of the SWAG factor out of LR shooting. I like the idea of ribbons @ different ranges. The hard part is watching the ribbons, then finding something in nature that reacts to wind speed in a similar manner. Good training.
