Just ran the quick numbers on a target at 4400 with my 375 CT. At that distance I need 133.4 Mils of elevation, at a 10 mph 3 oclock wind you would need to hold 4.3 mils. This is the intersting part:
Time of flight is 13.058 sec
Max Ordinance (the highest point the bullet reaches during the shot) 782.33 ft
over all drop works out to 1927.5ft
With how fast the winds change in a place like Kansis even geting impacts at that distance is a challange with the amount of flight time alone you are dealling with. At 16 rounds sent to get animpact is not bad at all. I believe the target was between 1 and 2 moa they are using, i will double check and let you know.
cheers
