During the great brass scare of '09 I traded into two bags of 1,000 pieces of 223 brass, primed with CCI small rifle primers. This brass is ready to load, and looks like re-primed once fired commercial brass.

Since I don't currently own an AR-15, my 223 shooting has shifted to mid-range work with my Remington 700. I'm getting good accuracy out of this brass with 24.5gr of Ramshot TAC and a 60gr Hornady V-Max, but would like to find out just how good the rifle can shoot.

What dies would work best for controlling bullet run-out and uniforming the necks of this brass? My rifle has a factory barrel, so I doubt I will have to turn necks, but I do want my reloads to be as concentric as possible.

I am already seating bullets with a Redding Competition (micrometer) seater die, which works great.
