OK, we can use a clip to load catridges (bullets?) into an AR detachable magazine, an 03A3 rifle's in-place magazine, or a revolver's cylinder. Is a speedloader considered a clip or a magazine or neither?
A clip is something that holds cartridges before they're inserted into a gun, which could be a source of confusion between a clip and a small-arms magazine.
I stand with the folks that say terminology is shared by a group so they can communicate between themselves any way they want, so it doesn't really matter if it's consistent. Now, when experts are trying to communicate with someone who doesn't know anything about a subject, terminology needs to be consistent.
To a reloader it makes a big difference whether a thing is called a bullet or a cartridge. To the guy that needs to load his gun before the other guy shoots him it doesn't matter what the thing is called. "Gimme some bullets" works just fine...
Try understanding drug nomenclature sometime. For every manufacturer name there is a scientific name. Take Lexapro as an example. For the typical person it's called Escitalopram to identify it on the shelf, but for the expert, it's called (1S)-1-[3-(Dimethylamino)propyl]-1-(4-fluorophenyl)-1,3-dihydro-2-benzofuran-5-carbonitrile.
