Nothing will be gained by any changes to the shell holder.
You are correct and I had to rethink why this works for me.
My comments hinge on me decapping as a separate step. I don't use the Lee decapper mandrel. If you do so as per the instructions, you can polish the mandrel to get a little more neck tension for resized cases.
I set mine up in a Forster Coax press that stops at the same spot so that no more or less force will cause any more or less travel in the die. Doing so allows me to control sizing and neck tension as per my own requirements. With the Forster, I don't have to mess with shellholder thickness, but I have done so in the past.
Depending on how you set up, you may have to rely strictly on consistent pressure. ...and, Lee cautions against the use of toggle or snap over presses due to lack of "feel". I don't like relying on "feel".
I'm not saying mine's the best way. But, I like the results.
Thanks for correcting me,
