how far are you intending on shooting out to ? I have a program that I really like to use with just a regular reticle , non bdc . .308 for me shooting coyotes would be 25 yard zero this will be 2.5" inches high at 100 and only 6" low at 300 more than enough to smoke a dog with . However if I was shooting paper for on center groups I would do it different .
a 200 yrd zero is 1.9" high at 100 and 8.3" low at 300 so the its really no better for my purpose than the 25 yard zero .
Dont ask thats just how it works

Military style rifles, with their sight line so far above their bore line, are entirely different when it come to zeroing when compared to standard hunting rifles.

Agreed. As I earlier stated, I zero hunting rifle at 100. since I consider 300 yards absolute maximum range for shooting animals, holdover isn't a problem.

My long range "social work" rifle, a .300 Magnum with target scope, is also zeroed to 100, but I keep a data sheet taped to the butt stock with the number of "clicks" for ranges to 800 yards.
