If you zero a .30-06 with a normal load of a 165-gr bullet at 25 yards with iron signts, it will be on again at 150 yards and about 2.25 inches low at 200.
If you zero the scope, set 1.5 inches high, at 25 yards, you will be about 2.25 inches high at 100 yards and on again about 215 yards.
I ain't guessing here, folks.
I have been doing this for more than 45 years.
Lots of my rifles are set up with iron sights and scope sights.
I don't set the first zero at 25 yards. I use a different method, but I know exactly how everything from my .22, to my .30-30, my .308, to my .270, works with a 25-yard zero, because I have tried it all, a long time ago.
But those of you who don't own a rifle, or don't know how to sight one in, can play with your favorite ballistics program on the internet. If your program, or favorite gun writer, is much off from my real world numbers, you'd be wise to quit believing them.
