Accuracy values for the main guns - MBT's.

[JaM]

Thats true, but there isnt a modifier for technological advancement. On paper, is soviet 125mm gun impressive (L48-50,1700-1800m/s muzzle speed...),but in reality it dont count. First gen soviet APFSDS were very unaccurate.Round of choice was HEAT,becouse it was more accurate and destructive. Western APDS rounds were more accurate than first and second gen. West APFSDS (M735,M111,M774...) I saw somewhere on Tanknet some data, where M60A3 in 1980 firing APDS was more accurate than M1A1 with M827 or Merkava Mk1 firing M111 (87% at 2000m M728, 84% M827 and 73% M111,but M111 accuracy is combat value from "1982 Peace for Galilee",accuracy during tests is always better) So for accurate accuracy :-) formula you need count with much more variables,but many of them are not public domain. (speed loss of projectile at distance,dispersion,quality of discarding sabot etc...)
