Expander & Choice of Powders.

Expander- Classic does not have one. A standard RCBS die set does. It will bell the mouth & expand the inside of the case to except the bullet. The expander is about .002" smaller than bullet diameter. The reason an expander is needed, most dies size the brass smaller than needed, so dies will work with all thicknesses of brass. The classic loader uses the bullet as an expander. As far as the 800x being use, is because, if more than normal is in the dipper, the amount over will not be enough to cause pressure problems. A much faster burning powder like Bullseye is not as forgiving. When you do not have a scale, 800x is a lot safer if to much is loaded from the dipper. Photo of expander>
