When you first take up reloading and read the basics at the front of the manuals it seems straight forward enough. Then you start to realize some of the more advanced and finer details for reloading practices are not so black and white.
To achieve the best results you realize you need to expand your reloading knowledge, buy more reloading equipment, spend time working up loads, measure/record everything, and maybe even buy a custom rifle. So much for cut and dried. Lol. But it is therapeutic and addicting.

With all due respect, the spring back after the expander passes through the neck is inward, toward a smaller diameter, so if you use an expander that is .003 under diameter, the resultant neck tension will be greater than that, not less. If you do not believe me, run the expander back through the neck and feel the resistance.

What you want is available. Whidden makes expanders in small increments and several die makers make bushing dies that can be used with expanders. The Whidden expand/decap parts also fit Redding dies.

When are they finally going to combine the expander ball with a bushing die?

If you don’t neck turn there is no way to control the inside diameter of the neck by using a bushing on the outside.

Expander balls should be available is different sizes in at lease 0.0005″ increments.
