Carbide expander button
By Don B. on Apr 30, 2026
I have been replacing all of my expander button with the carbide ones. I like the limited drag although I do use some lube too as I am just ocd with my brass. I like it with new brass I am AI-ing as I just run it through the neck, no lube and deburr. I get excellent .002 neck tension with premium brass like Peterson, Alpha or Lapua.

Great addition to any die, produces more consistent neck tension without additional steps
