Hello and good night. Currently I am doing a replica of an autocannon (actually a DEFA 554) which has two fire rates for AtA and AtG, and i wonder if its possible to use variables to achieve those rates when having the gun selected for air to air and air to ground depending of the time, also if its possible to add spread to the gun. thank you very much for any advice an dif someone knows a formula i sincerely thank for it
