Thats what I was thinking Guys its a bit much, I will measure both the Hornaday and once fired later just the cases to see if they are the same or similar, just checked they are much the same slight difference at the neck but thats it , just wondering if this so called Hornady is a genuine or a fired case drilled and tapped as the mate cant remember where he got it lol but surly that wouldnt matter if the cases where the same size etc the readings should be close driving me nuts will have another go later at measuring COAL and see how that goes lol
