I am going to try "bumping the shoulder" of my casings for resizing. I have primarily loaded for my 30-06 and a friends 22-250 in the past and have gotten away with neck sizing. I now have a 300WSM and have encountered problems with sticky bolts after a couple loadings. I noticed that most of the people here tend to bump shoulders. I would like to hear how you set your dies, ie, do you use a bushing to make a space or do you rely on your press stroke to be consistant? I noticed that my press is not consistant enough to rely on ( Lee challenger). Does anone use a press that is accurate enough to have a stroke within a thousanth or two to bump shoulders of your casings consistantly or do you all use bushings to make the gap? Thanks, Mark B.
