Thread: Interesting...

Im no expert by any means horihunter but I have found the same as you regarding case WEB expansion not head as this aint gonna expand unless something is really wrong? I thought the place to measure was about the place you would expect case head separation to happen.
In my rifle no difference in the above measurement from book min to well over book max and shaving brass of the head.
Primers seem to be unreliable pressure indicator also, fed crater at min load cci arnt even very flat when the brass has said "enough"
So now I just look at the brass. Go up till it extrudes into the bolt recesses and is shaved off on opening. Then back it of from there for the sake of brass life.

I am a novice! but this is what I have found so far I am sure I will be corrected if need be
