[Unclenick]

Jugornot,

The primer height I am referring to is from the bottom of the cup to the tops of the anvil feet. The feet are what touch the bottom of the primer pocket and the anvil tip needs to be forced 0.003" deeper into the priming mix during seating. You measure primer height gently so you don't accidentally get a bad measurement by starting to compress the anvil into the cup.

Consolidation (assembly into a unit) of the cup, mixture, foil, and anvil happens at the primer factory. Reconsolidation is that additional 0.003" of compression of the anvil into the foil and mixture. It optimizes sensitivity and consistency of the mixture combustion by pre-loading any cushioning by the foil (actually made of paper these days; the old cap and ball percussion caps used actual metal foil as a moisture seal and retaining cover) and uniforming the amount of priming mix filling the gap between the inside bottom of the primer cup and the tip of the anvil, which also affects cushioning of the firing pin.
