The bullet puller I have is a collet type. I have a collet for every size bullet I shoot. You select the proper size collet put the puller in a press, clamp down on the bullet and back the press off, out comes the bullet. I can pull lots of bullets in a half and hour. Did you get an inertia type (the ones you pound) or the type that clamps onto the bullet? The inertia type has an advantage when the bullet is seated too far in to get a hold of it with a collet, but other than that I like the collet type - no pounding.
