Remington cartridge for presentation?

Is this a cartridge whitch is for presentation on trade shows or sth. like that?

There is no primer bore.

Here some pictures:

It resembles a functional dummy which is made by ammo/gun producers to be used by gun sellers to have ammo to to allow customers the ability to check the action with out live ammo is my understanding.

I think by SAAMI Spec, all functional dummies sold as such by the cartridge manufacturers are supposed to have blackened cases.

This is more likely, in my view, to be a dummy made for a trade show display, or as a trade show or manufacturer’s rep “giveaway” cartridge. That would be a “presentation” of sorts, but that word conjurs up something a little more special than this type of dummy cartridge is, even though it is not totally an inaccurate discription.
