Stick, how do you headspace a barrel, off of a stick of 30-06 brass that you necked down to create a false shoulder for a 280 chamber, without a gauge. Did you just randomly create that shoulder wherever you felt like it? Measured from case head to false shoulder/neck junction and compared to a chamber drawing? Have a real gunsmith set the headspace and then create false shoulders to fit snug? It's pretty funny to see you make stuff up when you're discussing this stuff with people who actually know when you're full of it.
