223 80gr sierra loads
Looking for a good load for 223 using 80 gr sierra's in an AR-15. I am using either varget or 4064 for powder. This will be used for my 600 yd load. I know it won't be mag length.

Keep the OAL as shown or as near to it as your chamber will accomodate with a few thousandths jump to the rifling.0
