Why I ask is.... I have 25 rounds that have been fire formed to my chamber now. I neck sized them only this time around. Will that change headspace
(which I think it does ) and if so how will that affect distance of bullet jump ? I got my COAL to where bullets is .020 of lands full length resized. Since I use a bullet comparator with a modified case thats not fire formed to my chamber to set COAL I was wondering if it would make a difference. The way I see it is....since I didn't bump the shoulders back so therefore the case should be closer to the lands.
