[QUOTE="orch, post: 1326008, member: 35688"] I can't remember for sure what they were turning the 6.5 4s necks to for the "necked" chambers but I think they were taking them down to 0.0145" to 0.015"... 0.264" + 2x0.0145" = 0.293" hence the 0.291" bushing to give 0.002" tension in the 6.5 4s neck turn version... As far as the redding 6.5x300wsm non-bushing die being 0.291", redding has no idea what everyone's brass thickness is going to measure so they hedge on the small size and if the neck is sized excessively small the expander ball will bring it back up to proper size... it just works the brass a lot, that's why I have started switching to mostly bushing dies for must of my caliber since...
