Assuming the sizer is tight enough. Check that first. Size without expanding and check tension.Essentially, the diameter of your expanding die is the issue.
That is about where I would begin but I see it as a bit unusual you are having problems with both a handgun caliber (.40 S&W) and a rifle caliber (.223 Remington).The first thing to check is the diameter of your expander ... If it is too large ...it is a quick fix with a drill and some 600/400 grit wet/dry paper ....
My original .45 ACP sizer was too big for RP brass (Fine for everything else.) Same problem, not enough neck tension even skipping the expander. RCBS sent me a new sizer and it worked fine with everything. It was a bit tight though, really gave a pronounced "Coke bottle" affect . I use a Lyman sizer now.I have had no end of problems with .45ACP R-P brass from that lack of neck tension. It had very little even when I skipped the expansion step entirely.
