I have a L.E. Wilson bushing die set: FL die, Seater & head space gauge. I have .266" & .267" bushings with the .266" bushing currently installed. After sizing & trimming my brass I run them over a PMA Tool .241" expander mandrel for consistent inside neck dimension. I use a RCBS 6mm ARC taper crimp die for a light crimp on my gas gun ammo. No crimp for my bolt gun ammo.
