Useing my No 5 Nosler which doesn't have a 110gr .257 bullet listed, I used the 115gr CT Silvertip bullet @3400 FPS and 300 yard zero with a BC of .453. Into the LEE Shooter program I came out to:
100= +2.56
200= +3.22
300= 0
400= -7.80
500= -20.86
600= -40.10
700= -66.75
800= -101.91
900= -147.99
1000= -206.75
This is not your exact bullet and this is not your exact gun, it is a starting point to be able to be fairly close at those ranges.
As to the clocks I have dont it like this(but I might be wrong):
if 1 click = 1/8th" @ 100 than that would = 1/4" @ 200 = 3/8" @ 300 = 1/2" @ 400 = 5/8" @ 500 = 3/4" @ 600 = 7/8" @ 700 and 1" @ 800.
I might be wrong but that is what I have used to go out to 400 so far with my rifles and I was able to bring my groups up and to the left in about 12 shots, from 8" low and 6" right.
