Paul Lakowski Posted February 5, 2004 Share Posted February 5, 2004 I read that in testing modern APFSDS, the MV can change as much as 40m/s if the temperature is changed by as little as 5°C. THis is the reason that modern tanks have heaters in the tanks, to keep the ammo warm. But what about WW-II ammo or ATGunners...how much difference did ammo temperature make on Muzzle Velocity? Was there any thing gunners did to keep the ammo warm? 0 Quote Link to comment Share on other sites More sharing options...
Mr. Tittles Posted February 5, 2004 Share Posted February 5, 2004 I read that the German Elephant 88mmL71 had a problem where one of the ammo bins was adjacent to a hot area. The ammo would have a greater MV effecting the long range shot to shot accuracy. Come to think of it, if you fired off quite a few rounds, and then had a loaded round sit in the hot breech for awhile (lets say you were waiting for a tank to come back up from a gully), the round would get hot! you would not be so zeroed in. Modern day weapons take many variables like barrel droop, etc into account. There was no way the WWII tanks could. Modern fin stabilized rounds give up some accuracy from not being spun stabilized, but gain so much more from computers/sensors. 0 Quote Link to comment Share on other sites More sharing options...
