RCBS Lube-A-Matic Top Punch .558

RCBS makes this top punch for bullets with a .558 nose profile, so the punch face matches the bullet shape instead of flattening it during sizing and lubing. That fit is the whole point: less nose deformation and a cleaner result at the bench.

It works with the RCBS Lube-A-Matic bullet sizer/lubricator and the Lyman 450/4500 lube sizer. MPN: 85558 UPC: 076683855589
