[QUOTE="Barrelnut, post: 1409830, member: 74902"] Before the pros show up.... IMO all is really OK here. Your brass (actually your neck) is growing by .006 due to the brass flowing and being pushed upward by the die. (The brass has to go somewhere.) Having a cartridge with a 20% shoulder angle is more prone to this than cartridges with sharper shoulder angles like a 6.5 Creedmoor or WSM cartridge. You are really just gonna have to learn to live with it. I would make sure my expander ball was polished some and the inside of the necks were lubed good before you run them thru the die. The expander drags on the neck and can STRETCH it. Also, if it is good brass with consistent neck thickness, you can use bushing dies that minimally compress the neck and throw away the expander ball altogether. It's really the nature of the beast.
