I have been casting bullets off and on (Moore than on) for the past twenty years. When I ran the bullets thru my lubri-sizer, I had thought that I was shaving a microscopic amount of lead from the bullet while lubricating it. Now, come to find out, I discovered that I have been swaging my bullets. I seem to have discovered this while investigating powder coating my bullets.

My question is: if I am swaging (compressing) the bullet to a specific diameter, where does the excess lead "flow" without deforming the bullet base of nose?

Thanks in advance for your help!
