I am using a 140 grain Sierra game king in a 7 mm Remington Magnum CCI 250 magnum primer and federal Brass My only concern is I am thinking about using 67 grains of IMR 4831 that is one grain over max give or take than what most manuals say But what I was thinking is I have not set my bullet as deep as I once was. I was setting my bullet to the depth that the Sierra manual said to set it at but I have checked where the bullet touches the lands of the rifling and I have found that I was jumping it Just over a tenth of an inch So now I am wanting to jump it 20 thousandths of an inch so I would have more capacity in the case now so I figured it would equal less pressure so I was thinking about trying one grain more of powder than what the load data says. Is this dangerous? Give me your thoughts? Thanks
