[QUOTE="blacktail 8541, post: 1158359, member: 83713"] First of all it is ballistics in this case as you are describing atmospheric conditions. Mechanics as I stated in my post is applied to the physical act of firing the firearm. The maximum point of arc is determined by the velocity and projectile used. A summing a constant wind velocity across the length of the flight path to target with a 300 grain match king and a 2750 fps velocity taken from jbm ballistic app the drift would be 85.6 inches if zeroed on a calm day or 0 inches if sighted in with a 10 mph 90 degree cross wind. Max apogee would be 195.1 @ 750 wards. or 21.5 in. @ 10 mph There are a whole slew of variables that are present in shooting @ distance. Wind is very seldom constant. Measured at 1 foot or 20 ft altitude , 10 mph is 10 mph. Altitude barometric pressure,and temp all play a part. Terrain can cause a 10 mph to be blocked at points and increased at others due to funneling affect. If you want to discuss this further I will do so in pm. [/QUOTE]
