Thanks for all the replys guys, all makes perfect sense, just a question of balancing all the factors for the best effect.
Right, Ive got another question. When an AT gun was found to be underperforming i.e 2pdr its replaced by a gun with a larger diameter shell i.e. the 6pdr. The names of these guns suggests that its not really the size of the shell that is important but its mass. I assume that penetration is directly related to momentum i.e. velocity * mass. My question then is why didnt the 2pdr just get a heaver (i.e longer) shell, wouldn't that work just as well? What about HE, why increase the diameter of the shell when you can just make the shell longer and stuff more explosives into it?
