I’ve come across a 7mm Mauser round which I am having problems identifying. Below are pictures of the headstamp and side view compared to another 7mm Mauser round. The overall length is longer than the normal at 3.14 inches. The headstamp reads S B 18 O 95. Any help is much appreciated.
P.S. I hope the pics are visible. This is my first time as I don’t have access to the test area.
