Revolvers fire from a cylinder. Anyway, you mean magazine. Clip is the sheet metal thingy holding your rounds together, that you use to load some rifles. Probably the only weapon, that literally fires from a clip, is M1 Garand. Everything else has a magazine, be it internal (most bolt-action rifles and repeating shotguns) or external (pretty much every pistol, SMG or assault rifle).
DarkHedge said: MM. Nitro Express, namely .600 and .700 want a word with you. And yes they were revolver-designed ammo.
No, that's horribly wrong. They were designed as hunting cartridges for extremely big game - elephants etc. The only revolver in (the weaker) .600 Nitro is a joke - the ridiculous Pfeifer Zeliska thing that's so heavy it can't be even shot vertically without a benchrest. The most powerful handgun is actually the Maadi-Griffin one-shot pistol in .50 BMG, which accelerates much quicker in such a short barrel and gains much higher muzzle energy as a result - kinetic energy of a projectile equals half of its mass times velocity squared, you do the maths. And don't forget to count in the air resistance.
Also, this whole debate is pointless, because neither the Nitro cartridges nor the .50 BMG are originally handgun rounds, so the .500 SW remains the currently most powerful (and redundant) handgun cartridge.
