[QUOTE="Pdvdh, post: 1133181, member: 4191"] There's no way that much press handle force would be required to set a shoulder back 0.003". 5.56 brass is simply not that thick at the shoulder to generate that kind of resistance to being set back 0.003", in my opinion. The only area of a case that could provide that kind of resistance is down near the case head, at the base of your resizing die. So I suspect your resizing die has a tight diameter dimension at its base, and your once fired casings were fired in a chamber that was larger than average. Is this the first time you've resized .223 cases with this resizing die and shell holder? Are you certain your resizing die isn't bottoming out against the shell holder? If it is, there's a fix for that. [/QUOTE]
