seating a bullet core

How are they made? (Briefly)

My bullet cores start as coils of lead wire.  I cut the wire into smaller pieces and squeeze them into perfect little cylinders, so that they will fit inside the bullet jackets.   

I process fired 22 rimfire cases into jackets in stages. First, I sort the cases by headstamp, and clean them ultrasonically.  Next, I unfold the rims and heat treat the jackets.  Then, I tumble them in a bath with stainless steel pins to remove the crust that forms on the outside of the case during heat treatment.  The stainless steel pins also remove any remaining powder residue from inside and give the jackets a dull shine.  In the picture above, you can see a rimfire case with a lead core being seated into the jacket.  The lead core is pressed into the jacket under pressure. This is called core seating.
