Re: 7 mm Rem. Ultra Mag Range constants?
I am not sure if this would help, but if it does here it is.
An example for calculating wind would be like this: 3000 (range in feet) divided by muzzle velocity(2600)=1.1538 The real time of flight for standard air density would be (at 1000 yards) 1.7651 useing a 168 grain .308 caliber bullet. Then, 10 miles per hour times inches per second (10x17.6)=176.0 Next take the real time of flight and subtract the time of flight as if there was no apmoshere (1.7651-1.1538)=0.6113 This is the delay time, now multiply the delay time by the inches per second (.6113x176)=107.58 inches at 1000 yards
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.
