Confused about where to zero

...I will bet you that given a starting zero of 100 yards, your AMAX load will need about 3 minutes of elevation to hit (theoretically) point of aim / impact at 250 yards. This means shots that will be about 3 inches high at 100 yards.

If you shoot groups eight inches high at 100 yards (8 minutes), you have somewhere around a 450 yard zero.

I guess I need to go back and double check my values in the ballistic calculator I used. I think it was the simple trajectory from JBM, but I will re-compute. Thanks Bob & LR
