You might try annealing a couple cases and see if that helps eliminate the wrinkles when forming. Also, a couple of your dents (but not all of them) look like they might be caused by too much lube.
Finally, instead of a single trip into the forming die, you might try forming partway, then raising the handle, rotating the case a quarter turn or so, and then forming some more. This has helped me in forming bottleneck cases out of straight ones where I was experiencing that kind of dent.
