Who would imagine using a hammer-like implement would work for pulling a bullet apart?

Next to my new reloader (I am a novice), I have the "shelf of shame" for bullets I made that failed to pass inspection. I was getting distressed at the growing number of these (but that is a different story), so of course Jay introduced me to the concept of a bullet puller...a what??? So I bought one, "Berry's Superior Bullet Puller" to be exact. I'm pleased to say that it worked really well. So for those of you who are new to the reloading world, this video is for you.
