Guys, as a consistent 40k reader, I have to inform you that while your guesstimates about the properties are more or less correct, the standard Astartes bolt rond is in fact a .998 calibre shell. Imperial Guard bolt weapons used by infantry are both more advanced, to counter the recoil of a bolt weapon, but they are the .75 calibre ones. Heavy bolter are around 1.5-2'' in diameter, as we are talking about calibre here, which is measured in fractions of an inch.
