On another, that spent brass shouldn't be shaped like that, as it expands when the bullet leaves it--the expansion is what seals the area between the breech and the chamber, creating the pressure that propels the bullet out of the barrel.
Wait, what do you mean it's a fucking robot girl designed to fight terrifying monsters from another dimension and proper ballistics don't matter? :<
Case necks do expand (and the case also stretches in length, hence the use of sizing and trimming dies for reloading), but not to such a degree as to be readily apparent to the naked eye. If you're referring to the shoulders of the bottlenecked cases, they're supposed to be there, as with most all modern rifle (and some pistol, e.g. .357 SIG, 7.62x25 Tokarev) cartridges. You want to quibble about something, take up the fact that the spent brass looks fresh and clean, with nary a spot of gunpowder residue, discoloration, extraction marks or mouth dings. Or the bizarre ejection pattern. Or that the primers aren't punched (unless they're supposed to be electrical). Or that the bolt handle on her right gun/arm is apparently existing in two places at once. Or the tortured path a round would have to travel to load and extract from each finger/barrel. Or...

Well, Japanese gun (and weapons in general) laws are unbearably strict. While capturing the gist of the workings of a real gun, I think it would be understandable that a Japanese artist would miss out on the amount minutiae that you so sagely pointed out.
