When you are measuring your COAL with a Stoney tool for example, and want to bump off the lands by a certain distance what do you general use for Varmint rifles and hunting rifles? Stoney states to use .020 but Nosler book states to use between .015 to .030. I have been using .020 and as wondering if that is more jump than need for safe reloads? Also bullets vary somewhat so I presume I would need to get some jump to ensure that the reloads are not actually into the lands. I am just wondering if many people start with .010 from the lands?
