Cartridge is any complete, ready to fire, fixed ammunition (vs semi-fixed or separate propellant).
Bullet is any passive (not explosive, etc), not-finned or otherwise sabot-covered, projectile designed to be gyroscopically spun. Shot is (non-spin stabuilized) round balls instead. Projectile is the generic above that level if no other specific term (shell, missile, slug, flechette...).
Caliber is EITHER:
Diameter of the bore in whatever units, whichever conventional manner applies (as it varies).
OR, the length of the barrel in relative units, multiples of the bore size (not used in small arms).
(Since I do FOF stuff also: "pellet" is the general term for non-pyrotechnically propelled projectiles that do not obturate in the bore. "BB" is a size, .177" or 4.5"".)
