Mistaken Thread Title?

Hi administrators. I don’t want to nitpick, but we have a pretty current thread titled "Help to ID an inside-primed rimfire cartridge.? Isn’t there something wrong here? Aren’t all rimfire cartridges “inside-primed?” Perhaps isn’t this an inside-primed center-fire cartridge? As you know, I don’t know squat about rounds like the one the thread is about, but it just strikes me the title is either flat=-out wrong or at leas, redundant.
