You need to show us the end of the cartridge with headstamp and the coloured (blue if SmE) annulus around the primer.

Edit: OK, I realize you opened another thread for this.

JPeelen, yea, I tried to post a second picture of the head stamp on my original post, but it did not work. Nevertheless, here is the headstamp jpeg is again. I did a second post entitled “is this a SmE Cartridge II” with the head stamp picture. Thank you for the interest. Weight is 383 grains. I have not seen any SmE boxes for sale.
