The Lee collet die is ONLY used after the cases are fireformed to the chamber (as I said).
The "false shoulder" method will work with any case that has any shoulder.
As for 99 issues with the 250 Savage, 243, 22-250, 284.... the cartridges are all hot rods. The action was designed around a 30-30 class cartridge (303 Savage) and the action has a bit of "spring". In my 303 1899, cases last forever. In my 300 and 250 pre mil 99s, full hunting loads require FL sizing every time and brass is tossed after three reloads.
For those of old enough to remember when the 25-06 was still a wildcat, 30-06s were necked to create the false shoulder and fireformed with full loads. Chamber necks were cut larger, than today, as the neck was thicker than today's 25-06 factory brass. Bottom line is: the tighter the cartridge fits the chamber the less brass working takes place.
