[QUOTE="woods, post: 310285, member: 6042"] Hey tlk I do it just the way you said you did except I turn new cases. IOW, run a Lee Collet Neck Sizer into the new case to size it to the Collet mandrel and turn. I get a tight fit. The only thing I can think of is that a once fired case has a little more springback. When the case is pressed against the Lee Collet mandrel it will springback in an outwards direction. With once fired cases the neck will springback a little more than with new cases. You could anneal and hopefully that would restore the new case elasticity to the necks. You could order a smaller mandrell from Lee. You could reduce the diameter of your Lee Collet mandrel by spinning against some sandpaper. Pics would help. [/QUOTE]
