One way to improve ES is to get consistent neck tension. Shawn Carlock mentioned that lubing the inside of the case neck with graphite improves ES. Get a container, put some lead shot in, put some graphite powder in, push the sized case down into the container, inside case neck lubed.

Here are the sort of things to consider in getting consistent neck tension

The graphite lubing works reasonably well after cleaning cases with ultrasonics.
