rothirsch 3 point Joined: Jan 2015 Posts: 154 dale co.	Is your rifle chambered 223 rem or 5.56 NATO? Load based on the appropriate clambering. My Hornady manual has 223 rem, 223 rem service rifle( writeup says loads tailored for AR-15 chambered in 223rem. 5.56 NATO section cautions to only use these loads in AR-15 type rifles chambered 5.56 NATO. Be cautious as you go start low in the data and work your way up. Watch for pressure signs at each step of the way. Have fun shooting Last edited by rothirsch; 03/10/17 05:57 PM.

What is your barrel stamped/chambered for? .223 or 5.56? 5.56 is a much higher pressure round than .223 therefore it's much safer and acceptable to load/shoot .223 in a barrel chambered for 5.56 than the other way around. Once you determine this you should load accordingly. I firmly believe that a double gallows should be constructed on the East Lawn of The White House. Politicians who willfully and shamelessly violate their oath to uphold and defend the Constitution of the United States of America should be swiftly tried and, upon conviction, publicly hanged at sunup the day after conviction. If multiple convicts are to be hanged they can choose with whom to share the gallows or names shall be drawn from the hangman's hat to be hanged 2 at a time. NRA Life Member

So if your stamped 5.56 your GTG with either one you choose.
