dogzapper or others,
Now this is not the same as a neck sizer bushing right?
Nope, this is a little t/c ball that actually floats on the Decapping Rod. Normally, I lightly lubricate the inside/outside of the case neck and run the case through the die.
Neck Sizing Bushings, as BR guys use in Wilson arbor dies and Redding Type-S dies are heavy-walled hardened steel tubes and they size the OUTSIDE of the neck and are graduated in .001". The t/c ball expands the INSIDE of the case neck.
I'm a little surprised that the "Throw the Danged Expander Ball and Rod Away" gang hasn't arrived. The fly in the ointment on that one is that most guys don't sort their case necks for concentricity and regular dies also over-size the case neck down. You need the expander ball to expand the neck to a consistent inside dimension, so that the BULLET PULL is constant.
Handloading is simply plumbing. Open your mind, dealing with easy problems and easy solutions will arrive.
