I occasionally shoot the steel case TulAmmo through my 9mm pistols and its always worked well for me (for cheap range plinking). In the past, the bullet has always had a copper over steel jacket. I opened a box purchased a week ago (at walmart) to see that there didn't appear to be a copper jacket. The bullet was a light silver/gray in color. Did TulAmmo forget to put on the copper jacket or does anyone know if somehow they've changed the design/jacket of their bullet?
