Ok I am very strongly thinking about buying my first AR rifle. Most likely a RRA or Bushy in .223rem. I have been reloading for 30+ years but never for a semi-auto. I assume that full length sizing is always required. While looking at dies I noticed some say they are designed for AR rifles and size the base smaller. Is that needed or will regular FL sizing dies work. Thanks in advance. Paul
