This is probably simple for most of you on here but kinda confusing to me. I think I have been working in the wrong direction. The cross hair is zero first drop down is 1.5 second drop down is 4.5 third drop down is 7.6 fourth drop down is 11 this is in inches @ 100 yards Burris gives a drop chart for 100 to 500 yards and 200 to 600 yards but the 45-70 obviously does not match up to those yardages. How can I match the drop to the 45-70's more rainbow like bullet drop. I know the drop of my loads, just not how to compare it to the drops on the scope. Thanks all.
