    other signs a stamping on the brass, this is where the brass has "flowed" around either your ejector or maybe extractor port - you will see it on the case head - it will be shinny
    Dont waste your time chasing every last fps, it doesnt matter in the real world, it wont make a difference, all it will do is cause head aches and frustrations. And dont listen to silly old cunts

    can be cause by brass being abit out of spec for your chamber, if bolt lift is good and primer ok then not to worry about
    its best to do your higher end loads with brass already fired in your chamber
