And I mean by long range, I'm not talking about lets take a guess it's a 100 yards and squeeze one off in hopes of hitting it.

I'm talking about knowing or wanting to know what all those little hash marks in your scope mean.

Knowing and learning what Mil and MOA mean.

Example, using you SCR MIL scope, finding a target and knowing how far your target is.

Lets use your average human. Your average human is about 5"8" that converts to 68". Now using your SCR Mil scope, you zoom in on someone, and that person is now 4Mils tall.

You take that 68" x 27.77 = 1,888.36 divide that by your Mil of 4 and you get 472.09 yards away. Now you dope up in order to hit said target.

The smaller the Mil, the farther your target is, the larger your Mil, the closer your target is.
