What is your approach to selecting a bushing size for a bushing die?
I have measured fired casings and new commercial loads to determine before and after neck diameters.
Clearly new cartridges vary by manufacturer,
I assume this ties to brass dimensions and tooling.
How do you determine your what bushing to use (there is a range for each caliber)
Clearly oversizing works the brass more and may create more neck tension than is desired...
Tell us,a bit about your process.
