I use to do all that sight in at so many inches over at 100.In find 99% of the elk I shoot are less than 100yds.For years I have set my .06 at zero at 100 yds. This year,one elk was at about 60 yds,the other was at about 80. Two deer were at about 70 yds.
Of course if you are always in the open country ,things would be different.
I was with a guy who was shooting a 300mag, miss a ram of a life time because he was sighted in at 3" high, shooting uphill, at about 100 yds. He blew one over right it's back and subsequently shot a smaller ram, and almost missed it the same way. Just barely creased it spine.
I'd much rather have my rifle shoot exactly where I am aimimng when I know that realm is 95% of my shots and then compensate for the other 5% than pick a random number and never have the rifle shoot exactly where I aim at any distance
