Thread: FL sizing without expander ball

Agreed that expander buttons can cause run out as they are pulled through the neck, but I can’t agree that expander mandrels necessarily do the same. I expand my necks with a mandrel then size with a bushing neck die. With turned necks I typically get single figure 5 shot ES. Two nights ago I checked zero and mv on my .284 Win for a hunting trip this weekend and had an ES of 2 over three shots.

We all have our methods, and I’m sure there are other ways to achieve great results, but my way works for me.
