The only thing flawed here is your over active ego.

Too bad your so full of yourself that you think you know more than anyone else.

Meaning the Internet is full of midgets sitting at their computer pretending to be giants.

I wonder how many reloader have "any" type of pressure measuring equipment.(less than 99.9999999999999999%) The rest of us look at the primers or measure base expansion.

You said my "E" above was not true and yet if the case capacity on a .223 case varies from 28.0 to 30.6 with the same powder charge there is 6,000 psi difference in chamber pressure.

Oh my, that must be why they tell you start low and work up your loads, too bad that advice is so flawed for the people without pressure measuring equipment.

I have to go now, I'm going to neck down a 30-06 case to .270 and blow up the world. (darkker's flawed theory of brass strength and reloading)

Have a nice day............Dude
