It doesn’t have any of the shape a casing has. There’d be a flared base, for example. This doesn’t have that. It is a painting though, not a picture, and the colors aren’t accurate. The shape is consistent with no casing though, so I’m betting that the color is just not quite perfect.
Edit: This is what a bullet+casing looks like. The shape is totally different.
There’s a clear color change from copper to brass, bud.

Note the bullet to casing proportions are the same as the image, including the inset of the casing that narrows to the actual bullet.
OK, I don’t understand what’s going on here. It plainly is not. Seriously. Compare them side-by-side.
