Re: ? on bullet drop at 600yds
Can I ask what kind of load you are shooting?
According to my math, you need a bullet with a BC of .525 @ a velocity of 3600 FPS at sea level at 59 degrees with a 100 yard zero and 46" of drop at 600 yards.
I dont know of much that will do better than that.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
