Mandrel vs Button vs bushing

[General RE LEE]

I anneal my brass in an AMP and then run it through the good ole Hornady New Dimension FL die with expander ball bumping shoulder 2-3 thousandths. Trim if needed, tumble to remove any die wax or lube, prime, load and seat.

Ive gotten exceptional accuracy with this simple method but I also am not competing. I've never got into using bushings for neck tension. Instead, the AMP softens the brass to a high level of neck tension consistency.
