accuracy should be calculated for all with the same formula as stated in MOBHack help
Quote:
Calibre Length, ( the effective length of the barrel (from breech to muzzle) divided by the barrel diameter is the Calibre Length value) is then divided by 4

so, a Panzerbüchse 39 has a Barrel length of 1085 mm and a barrel diameter of 7,92mm
1085 / 7.92 =136.99 /4 = 34.248 round down to
34
