Home Forums Hunting & Shooting AR and Tactical Rifles Which .308 dies for AR-308??

I have used both. You don't need the small base dies. I check every piece in a Wilson case gauge. If the brass will fall in the gauge, you will never have a problem. I loaded 500 pieces of once fired Speer 223 for an AR with out trimming. Dumass mistake! Had to shoot it up in a bolt gun. You might want to check length. Dont learn the hard way. Case gauge good for length also.
