So interesting results with them seated out to the lands.
First 4 shots all ok with slightly cratered primers and with the 5th I got some primer spray in the face as it blew.
Primer was dead flat and a hole in it... It was at max load but had worked it up as they were safe just short of the lands.
So I'm guessing I knock back the charge and try them seated out as there is only marginally more effort to close bolt so they are certainly not jammed in there?
But, there is clearly more pressure with a blown primer....so go up in 1 or 2 grain increments?
