Royston, I think that maverickrazor is trying to say that he is quite clever and not a sad balding loser who got his Mum to pay for a trip to an exotic beach once and is now hoping for cyberfame for his learned wit.

you have a point to some degree. However don't forget that the rounds of ammo have driving bands. This is where the round is almost as large as the calibre of the weapon but not quite. The hot gases that are released when the cartridge fires are what drives the round out of the chamber/barrel.The round has to be smaller otherwise the chamber would explode as the hot gases expand. The spiral groove that is scored in the barrel is called rifling and it causes the round to spin very fast thus eliminating contact with the barrel and greatly improving accuracy. I hope you don't think I'm teaching you to suck eggs as that is not my intention.
