Hello I have a question regarding bushing size for a redding FL bushing die I purchased for my 300wsm. I measured the neck of my adg brass with a loaded Berger 180 Elite hunter. .340" I'm also starting to use an expander mandrel for neck tension at .306". So am I right in thinking I want my neck size before using the expander Mandel to be around .304-.305 so that I'm working the nrass as little as possible ? What do you guys recommend for a bushing size ? I'm thinking 3.36 would give me 4 thou neck reduction and leave room to expand 2 thou with my expander mandrel ??
