    What do you see that makes you think there not seated and is it always the same with all cases and all primers?

    When i seat the primer and place it on a flat surface it wobbles around. I triend seating and turning and seating again several times to see if its an edge that doesnt seat (i read to try that somewhere) and no luck. Plus when i run my finger over it its obvious that its not fully seated. Ive thought maybe the shell holder isnt holding the case tight enough?

    are you cleaning the pocket before you seat a new primer ?

    Use a primer pocket uniformer to be certain the pockets are square at the bottom.

    It takes quite a bit of pressure to seat a primer with good brass. You say you're having the problem with different brass different primers and different tools. My guess is you need to apply more pressure. You can actually feel the primer seat in time even using the RCBS Press priming tool.
