[QUOTE="Bart B, post: 722481, member: 5302"] Right off the bat, I believe case head extruding into holes in the bolt face is a "real" indicator of pressure being too high. Typical cartridge brass starts to extrude at about 65,000 CUP to 70,000 CUP; that's about the same as about 85,000 PSI. There has to be something different between your dies and techniques to cause that if the components are the same. Probably a dimension someplace. So you've gotta measure everything between the two sets of resized cases from each tool and process as well as the dimensions between the loaded rounds of each. Every detail dimension wise should be checked. [/QUOTE]
