I'm planning a 243 wssm build and want to shoot the 105 AMax out to 1200 yards. 900' elevation, 75 degrees air temp.
Questions:
In order to keep pressure down and also be able to shoot lighter bullets on occasion, what is the minimum twist I can use?
What muzzle velocity is needed to stay above trans-sonic to 1200 yards?
