One thing that will cut down your ammo expenditure on long range shooting like that is to bracket the target rather than sneak up into POA=POI.
The same applies to zeroing. After your first register, make a gross correction. That will give you a much better idea of how much you need to dial to get on.
Also, start out with a good ballistics program, know your mv, baro pressure, and temp, and input those variables. If there is Litz data for your bullet, use that and use the G7 drag model, not the G1. Ensure that you use the G7 drag model option on the program before entering in G7 BC data.
Know how to call the wind, and watch carefully what the wind is doing along the path of the bullet, then make necessary adjustments.
