Found 3 spent cases at range and never saw before. Guess used in .410 and Russian shotgun ammo? Looks like it could be nice leather hole punch!
The photo of the box shows both. Right below the .410-3" Magnum it shows (.410/73 Magnum)Interesting headstamp: the diameter is given in inches, (.410), but the length is given in mm (73). The photo of the box that Taylorms attached shows the diameter and length given in inches. I wonder why the maker of the brass would mark it that way?
Nice find!!!!! Could even be THREE NICE LEATHER HOLE PUNCHES! OR...as you say..one leather hole punch...and two brass Whistles for calling Cow Elk....orFound 3 spent cases at range and never saw before. Guess used in .410 and Russian shotgun ammo?

My best guess here is that the case is the whole length of the chamber so there is no room to have the bullet protruding from the end of the case mouth. Based on the shape of the crimp, I'm guessing the bullet is tapered rather than flat. They likely crimped it down like that to aid in loading and to remove both the potential sharp edge of the case mouth and the gap between the bullet and the case that could have something get caught in there that may or may not cause a pressure spike.BradyT88: I saw that, but was surprised that is what showed up in the headstamp. I think you're right about .410 being so common worldwide that it is considered the name more than the diameter.
It also appears in the photo that Taylorms posted, compared to the photo that muddyboots posted, that the brass is crimped significantly. I would think that would make it harder to reload --- meaning reforming that crimp on subsequent loads would work harden the brass. Why use brass if you're not going to reload, and why crimp so significantly if it is intended for reloading?
