If you have a kinetic puller, you'll notice that the shell holder is about the same size as the collet. Tape it on if you can't get the threaded nut on over the shell holder. Put the whole thing in and pull the bullet then seat the primer deeper once there is no more powder and bullet.
I have reseated a few primers in loaded rounds before, but I always feel pretty nervous doing it. Although I've never set off a primer seating it, you never know.....
