if its for your bag gun Dan, you can fire form the brass in the barrel you put on the gun ,word is the new barrels need 50-70 rounds to settle down anyway,fire form ,load a grid and your good to go.
you might want to get a sizing reamer that matchs your finish reamer from Kiff,buy a die blank and make a sizing die,a little bit of expense but well worth it.if the sizing die's you have are the ones you had in Phoenix at the nationals they may not be optimum.if you Look in Boyers or Ratigans book they explain how to tell if the sizeing die is good ........or scrap.
Hope that helps.
See you at the range
