Neck sized for about 40 years for all manner of cartridges and have never had to bump shoulders. If it came out of a chamber, it always goes back in. All cartridges, however, are rifle specific. Once had a pair of 270's and a cartridge cross over could go one way but not the other.
This is where I'm at. "Partially sizing" for 6 .250 Savages here. I DO keep my brass separate for each one. Three .270's. Same deal. Multiple .22 centerfires (even in same caliber) likewise.
I DO FL size for the 4 .30-30's here, and do not dedicate brass to a gun. Reasons should be self evident.
My great concern with this video was that someone just getting into reloading will take the misunderstanding conveyed (cultivated, actually) in the film that shoving that brass all the way into a die every single time is the gospel now for accuracy.
Most here have learned that is NOT true,
I appreciate all the participation in this "firestorm" I did not expect!
