[QUOTE="Bullet bumper, post: 818628, member: 17844"] I agree neck length is not as important as neck squareness . However it's one of those minor case prep jobs that is hard to prove that it helps all by its self . I find it helps bullets seat straight and bushings size straighter . Start with a square well chamfered neck is basic in my system . Most factory chambers are around .015 to .020 longer in the neck area than factory brass anyway . I don't trim to an actual length it's irrelevant to headspace , seating depth or OAL . I trim to slightly shorter than the length of the shortest case in a batch so they all come out square and the SAME length . When you seat a bullet you set the OAL or seating depth whichever you are working with , either magazine length or ogive distance from the lands . [/QUOTE]
