I'm pulling what little hair I have left out trying to get this combo to bump the shoulder on my 300PRC once fired Hornady brass. I'm setting up my just received Zero press with the SAC sizing dies, beginning with the 300PRC. I've followed the video instructions, used the lowest Redding comp shell holder I have (.002) and added a 13 shim stack to the SAC die, no bueno. Has anyone else experienced the inability to bump a shoulder with this die?
