Re: 30 CAL 180GR coefficient data help

I am using .524 in my 12x 300 RUM based on double chronies AND drop tests out to 725 yards.

Actually, that is the ballistic tip that I am using. The AB should be very close but possibly different.

.507 has always seemed low, not only mathematically but also in the real world.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, 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.
