Ok, I've got all my brass for my 6-250 trimmed, neck turned and sorted. Now all I need to do is size and prime. I have .265", .266", .267" and .268" bushings for my Redding die. I measured the neck diameter of a loaded round and it measures .268". Obviously this leaves out one of the bushings but which one of the others should I use? From your experiences does more or less neck tension make a cartridge more accurate. Keep in mind that this gun is primaraly a bench gun and the magazine will never be used. I don't mind a very light neck tension as long as I don't have to worry about the bullets settling or runout increasing due to normal hauling around. Thanks in advance, B.J.
