> А вот после войны таки была серия пилотируемых мишеней на базе истребителей "Кингкобра"(усиленная обшивка, аппаратура регистрации попаданий и т.п.); для стрельбы по этим самолетам использовались специальные боеприпасы.
А что про это можно подробнее почитать? Особенно про боеприпасы.
Left, one more unusual type of ammunition was this T-44 .30 frangible round. The projectiles were made from a mixture of lead and bakelite, and trainee gunners fired them at specially armored Bell RP-63 Kingcobras. Despite the RP-63's armor, muzzle velocity had to be kept down to 415m/sec, and the recoil-operated Browning .30 M2 guns needed some gas assistance to function. Gunsights and aircraft speeds were chosen to give trainees the correct "feeling" of the .50 that was the standard USAAF armament of the time.
