Thread: BIT OV BOTHER..

Hi peoples,
Lately I've been back playing with the .223 and enjoying it,been a long time.
Anyways I'm loading up a few using BM2 powder and 55grn SP pills,cci primers.
The manual says the start load is 24grns and max is 26grns.
First three loads done at 24grns....very accurate...not speed tested.
Second three loads at 24.5grns....verry accurate....'' '' ''.
Third three loads at 25grns.......very accurate.... '' '' ''
Fourth three loads at 25.5grns......very accurate... '' '' ''
Fifth three loads at 26grns Max very accurate '' '' ''

Now for the punch line....All loads from the first three to the last have cratered primers.
No other pressure signs at all just craters. Pills are all seated to factory specs.I even tryed these loads again with pills seated just off the lands,no different,same results.
To be honest I cant understand why they all hit the same spot.
Any ideas why the primers are cratered on all loads?
Any reason ??
Cheers.
