[QUOTE="J E Custom, post: 1954478, member: 2736"] Testing Is the only way to find out how much jump you rifle likes. the main advantage of more jump Is normally velocity and less chamber pressure or both. Bullets should not be jammed In the lands for consistency, but they can be touching. Most shooters start with .010+ off the lands and increase until the accuracy node is found. Jump can range anywhere from zero to over .100 thousandths with some exceeding .150 thousandths. I would recommend that any Magnum should start @ .020 and go + from there with more and more seating depth because of chamber pressure. J E CUSTOM [/QUOTE]
