Lube it and size it in the 6TCU die set. I make sure I deburr my brass first, especially on the inside of the neck. Just makes it easier for that tapered expaned to slide in and out.
Load with moderate load and make sure the bullet is at the rifling so you get a good fireform. If loaded right, your fireform loads should be fairly accurate also.
Good Luck

P.S. I have about 100 in my loading room left to finish flash holes. When done, I get to load all 500 recently sized brass for fireforming. Yahoo. Prairie dogs etc watchout.
