    Has anyone upgraded the "cutter" on the worlds finest trimmer? Three of mine have chinese 4 flute hss end mills, but my 308 / 260 trimmer has an even cheaper 2 flute end mill that tends to grab my brass, especially on the first trim when I have a lot to take off (1x fired LC).

    My machinist says a 5-6 flute carbide mill would be great, so Im going to add a couple of them on the next tooling order.

    Has anyone tried this yet? Also a drill mill looks interesting as it could chamfer while it trims, but not sure if it would make a burr on the outside or bell it out. Thoughts?
