Yep, when the anvil legs make contact with the bottom of primer pocket this moves the anvil closer to the bottom of the cup, thus sensitizing the primer.This reference is to the Boxer type.The primer or igniter ignites the powder by heat rather than shock. Altho the priming compound seems like an explosive rate, the powder is actually ignited by heat from the flame rather than the shock of the priming compound which ignites at some 18-20,000 fps.
