The collet fits into the bottom of the die body. RCBS makes some 20 different collets to accommodate most any popular caliber. They are typically available for under $15, depending on where you shop.
Following the instructions, I started out by threading the die both into the press several full turns, as shown in the above photo. I quickly determined that I wanted to be able to see the collet engage the bullet so as to ensure everything was set properly. As it was, that was all going to occur up inside the top of the press, out of sight. In order to allow me to view it, I threaded the die body much furhter into the press.
In this photo, you can clearly see that the die body is threaded much further into the press. The collet is actually protruding further than it will when it is tightened around the bullet. I wanted you to see the bottom of the die and the collet here so you have a clear understanding of what the business end looked like.
By applying several turns to the bullet puller handle (top of the die), the collet was pulled further up into the die. At this point, I raised the ram of the press which placed the bullet fully into the collet. At this point, the handle was turned until the collet firmly gripped the bullet. Knowing that this NATO cartridge had sealant on the bullet, I followed the suggestion in the instructions which said to "seat" the bullet about .005" down into the brass before trying to pull the bullet. Doing this helps break the sealant's bond between bullet and brass. It worked.
With the sealant bond broken, it was easy to lower the ram on the press and pull the brass off of the bullet that was securely held in the collet's fingers. You can see the bullet still in the collet in the above photo.
Here are the results of a successful pull....the brass, the powder (mostly still in the brass), and the bullet. You can clearly see the dark colored sealant on the lower half of the bullet. There was the slightest mark on the bullet from the collet. I doubt it would cause even a few, if any, issues when reloaded and shot. It's not likely there would be any mark if this were a regular hunting load or a hand load.
So there you have it....two methods by which to extract a bullet from a loaded cartridge. Quick and easy....doing just one or two, I would use the kinetic puller. If I were pulling more than a few, or had stubborn military rounds to disassemble, I would opt for the bullet pulling die/collet setup.
