Utah, are you resizing coiled brass cases or resizing drawn brass cases? It's a little unclear.
Mike,
I am resizing modern .450 NE cases to fit a Joh. Springer rifle with coiled brass chambers. The 'double taper' is a PITA doing it the way I am. My machinist friend is making me tapered sizers that only do one dimension so it is taking multiple steps and I need at least one more sizer made. It is free doing it this way vs. the $500+ for custom dies.
Once the cases are fire formed in the chambers I'll only 'neck size' them.
