400 yards is easy to tell--it is the distance from the crosshair to the bottom post on a Leupie fixed 6x (18", or chest depth on a deer). Instant range finding.
Same works for a fixed Leupie 4x, only that makes it about 275 yards.
Keep it simple.
DD,yes agreed...but to my eyeballs it looked like the 6X was subtending 5" at 100,so that is what I used as a guide...really close enough but you are likely right.
With anything doing 3200 fps,and zeroed for 300 yards,the bottom post of the 6X is my aiming point at 500 yards.It works good!
