I have made cannons for the f6f, and used the hispano 20 mm and hispano 20mm round, when i shoot at an aircraft it takes nearly 200 rounds to down the E/A, and when i fly in the typhoon which uses same gun/round, it takes about a dozen rounds to destroy E/A. i noticed this with the 30mm i made for the bf110 as well, i have uprated blastsize ect. but dont seem to notice any change,is there something amiss when you have guns as load outs compared as to when they are modeled into the plane.
