[QUOTE="Bart B, post: 1124459, member: 5302"] BigEd, I'm not sure I understand your comments about case necks sizing and bending and expander balls. Here's a situation..... Loaded round has neck walls with a .001" in spread thickness. It's a 30 caliber cartridge with a .308" diameter bullet in its neck. With neck wall thickness averaging .013" thick, the loaded round's neck diameter is .334" average. Firing that round expands the neck to about .338" diameter in a chamber neck that's about .344" diameter. Sizing that neck in a gelded die (no balls) with its neck at .332" diameter has the case neck perfectly round at that same diameter while the neck is still in the die. It's mouth inside is now a little oval shaped with a .306" average diameter. What's the inside and outside dimensions of that case neck after it's pulled out of the die's neck? What's the inside and outside dimensions of that case neck when a perfectly round .308" diameter bullet's seated in it? [/QUOTE]
