Set up a toolhead to load boolits from a Lee 358-158 RF mold. I'm not a fan of the mold but like the boolits from it. The meplat is huge. The seating punch didn't fit so I thought, "No prob; open it up on the lathe." Find a 1/4 tool bit and grind it to reach inside the seating punch. Figure out the angle. Figure out the depth. Opened up as far as I dare the edge of the punch was now sharp and the meplat still didn't contact the flat center of the punch. It was still contacting the ogive. Shortened the rim of the punch until everything fit, polished and smoothed the edges. Tested it on the Dillon 550. No more marks and gouges on the ogive. Good start.
Get out the new RCBS Cowboy dies. Since the Dillon has its own expander that may defeat the purpose of using the Cowboy dies but they sure are purty. They're heat treated to a brown finish with brass lock rings and set screws. Installed and adjusted the sizing die and used the seat/crimp for crimp only. Loaded about 3 dozen rounds with 2.8 grains of Bullseye to try. I've shot lots of wadcutters using 2.3-2.8 grains of BE but this mold is new so I haven't shot any of its boolits yet. I'm still working on a cardboard canister of Bullseye with the plastic plug cap that I bought in about 1982. The price was $9.45. Primers were 69 cents/100. I never dreamed of buying a thousand at a time back then. The primers were consumed as soon as they were bought but the Bullseye still works the same as new.
