It's better to not add grog/temper if you don't have to. The reason they use it for bricks and pottery is because it reduces thermal shock, increases wet strength, and minimizes shrinkage. The latter is the opposite you want for a bullet. Grog can also reduce fired strength as well. As long as you dry them properly first, and warm them up slowly, then the finished result is better. They're smoother too, which means better aerodynamics.
