but I do understand the need for 100% reliability. I am only loading for range practice/target shooting,
Will store these for SHTF and will require 100% reliability.
Snipped a bit to get what I want.

Usually the seating die is manufactured with a "roll crimp" built in. If you are reloading for a semi-automatic pistol the headspace is controlled by the case mouth and you should not roll crimp! That is why Lee makes the factory crimp die and others make a taper crimp die. I suggest you delete the seating/crimp step and use a separate crimp die. You'll get better results.
As for flaring or belling the case mouth, use it sparingly and only flare enough for the base of the bullet to just enter the mouth without shaving.
In any kind of a match or SHTF scenario you don't want to have to deal with any kind of a failure.
I don't generally get very many that fail either the gauge or the dismounted barrel. 10 out of a 300 round reloading session would be many more than usual, so I'll check for obvious faults like cracks, bulges, length, out of round. Then I pull the bullet and recover what components I can, sometimes the case is salvageable, sometimes not. So to answer Franchi20/28's question if they fail the gauge they don't get used.
