Much depends on the numbers used, ie: bullet design and weight/length (BC) & initial velocity.
With a 1000yard zero, these are some numbers.
550 yards 493.23" high = 1,000yard zero
At 550yards, the bullet is 493.23" (41.1feet) high for a zero at 1,000yards - according to the 'chart' I have.
It would have been 156.24" (13.02feet) high at 100yards.
That was for a BC of .450 (estimated) with an initial velocity of 1,250fps.
If that same load was zero'd & aimed at 100yards, it would be -1557.34" (129.8feet) low at 1000yards.
