If I go to buy tires for the Jeep and ask if they have wheels in ___ size they will start looking for metal things in that size not rubber things.
Do you actually want to put money on that. Walk into any tire store and give the correct dimensions of a tire and call it a wheel. I'll bet they bring you back a tire.
Example - ask for a 275 60r 16 wheel. They will bring you back a tire that will fit many different cars, specifically the 2000 impala from memory.
You could probably ask for a 7.5 x 16 5 lug tire and get a rim or wheel fitting that same description.
There is being right, and then there is effective communication. For the firearms where there are actual separate clips and magazines (sks anybody), then using the right term is probably a good idea. Especially if it is in a situation where being handed the wrong part is possible. In the shop while performing repairs, you are in a technical conversation (more on that later) and you very well could mean either one so use the right term. On the range, where you are more likely talking about the clip than a magazine (assuming a non-detachable magazine on the sks). On the range where you have a detachable magazine on your sks, call it either. Unless you are using clips to load the mags... then be specific. On the range, where my cz only has one of the two... call it what ever you want. There is only one possible part you are asking for and your point gets across effectively. That is how communication works.
And to what is correct... Merrium Webster disagrees. You can argue till you are blue in the face, but unless you really want to argue that the dictionary doesn't have the correct definition of a word, you are the one in error. Yes, there is a difference between technical definitions (such as legal) and common use. If you aren't in a technical discussion, it's probably safe to assume that the common use definition in the dictionary is being used.
CLIP:
2: a device to hold cartridges for charging the magazines of some rifles; also : a magazine from which ammunition is fed into the chamber of a firearm
and there are still clips that are used to load modern magazines.
clips load magazines,magazines load chambers
Thee words for ya. M 1 Garand. The clip is removable and place in the magazine. The rifle is loaded directly from the clip.
Keep in mind this- The use of improper terms sounds unprofessional. Who do you think will do better in a job interview or in advancing their career- One who clearly communicates using the correct terminology, or one who is mis-understood from using a word incorrectly because "it's common usage"?
- To this, I say: There is a time and a place for everything. When attempting to prove superior proficiency, using the correct terms is probably the best avenue. When in a common environment, by which I mean an environment where you are not trying to prove your superior proficiency (unless you have to be the alpha), then common usage is acceptable. For most people, I would assume they have nothing to prove. We don't work in the firearms field and we have no need to prove superior proficiency with words when we speak. If you want to measure my proficiency, check my targets.
OH, and for those that do say Websters Dictionary is incorrect (and has been for years), please state an acceptable source for your definition. Last I checked, that dictionary is used by millions of people and it's definitions are considered to be fact in academia. So if Websters dictionary is wrong, what authoritative source are you using? If you consider yourself the authoritative source, why should the rest of the world use your definition vs. Websters? Please be specific and post something more substantive than "because that's what they are" or "because my drill sergeant/instructor said that's what they are called".
