WesWorld

[SIZE=3]Note:[/SIZE]

As "BigGun" lists WW1 shell factors as 0.6 to 0.8, and WW2 shell factors as ~1.0, all Indian shell form factors start with 0.8 as their baseline in 1918, and increase by 0.01 for each year after in 1918 in which the gun is introduced.

Therefore, the 10.5cm/1918 has a shell-form factor of 0.80, while the 12.5cm/1924 has a shell-form factor of 0.86.

Obviously this puts India at a disadvantage when faced with Wesworld 1920's vintage artillery using superheavy shells and shell-form factors in excess of 1.0; but from a historic perspective, it seems realistic.
