I've got to the bottom of my "once fired" brass bucket. I've noticed that on about 1 in 20 or so, the round chambers significantly more snug than the others. The case lengths are all in spec, so I'm guessing that my shoulders are starting to creep. .308, fire formed. Only got the one rifle.
I've been using a Lee Collet neck sizer along with a redding bullet seater; was using a redding neck sizing die, but a quick check of concentricity turned me off of it. This combination's been working well for me. May be a dumb question, but is there a die that will just bump the shoulder, and leave everything else alone? Or is there a die that will bump and neck size like the collet, and leave the body alone? Or should I just try something else? I'm going to the hardware store tomorrow to buy a spacer so I can start pulling some measurements.
I'm to the point that whatever I load will be twice fired brass, so inherently this problem is just going to be more prevalent as time goes on.
Thanks guys,
