Meh p40's all had thick skins.
After the zekes 20mm runs out,its basicly chicken peking from there on out, unless the zeke is maby 300 yards out,his smaller guns would have more impact and MABY then brake thru. however from 800 out, no way..most if not all your ammo would simply BOUNCE off,something aces high doesnt model for PLANES ,range air speed,and deflection.
The end resault of a zeke fireing at from long rang at ANY p40 without useing his 20mm would be a nice fire work show from the rounds and tracers sparking.
Saw a gun cam once where one p40 flew RIGHT thru another p40's line of fire,needless to say that p40 sucked up the damage,and kept on truckin' you could SEE the panals flying thru the air as they blew past the fireing p40 "the guy who shot just as his buddy ziped past" and even tho the other p40 soaked up 3/4th of the total ammo spat out in under 1-2 second of fireing,the remaining rounds hit accuretly on the zeke the two had been chaseing, end resault..a scared p40 and one flame ball for a zeke.
wingtip to wingtip it sucked up all them rounds and kept on truckin'.
The only thing im not sure of is if the planes are p40b's or p40e's most likely e's granted the tracers came from the leading edges, but maby it was a B, with only his .30's fireing.
in any case,he too was chicken peking the zeke,so...."shrugs"
but the way the zeke blew up, with the amount of ammo "total" of the burst that did hit it, looked more like 50's..maby it just hit a nice spot.
Yeah yeah,so i love the 40.
