How much does Quenching increase Cast Bullet Hardness?

How much does Quenching increase Cast Bullet Hardness? If you've been following my articles for any length of time, chances are you already know I water-quench virtually all my cast bullets. While the fact that quenching increases hardness is fairly well known and agreed upon, I've always wondered just how effective it really is.

Quenching and tempering of steel

This process is then just called quenching and tempering ("strengthening"). When tempering at low temperatures, the steel retains a relatively high hardness and the steel is referred to as hardened steel (wear-resistant steel)! Tempering at relatively high temperatures leads to increased toughness with still increased strength!

Hardening Mild Steel

Mild steel can be either case hardened ( a thin layer of carbon will be absorbed by the steel and it will make for a hard case with mild steel inside - hence the term) and WORK hardening. . .which is done by beating the steel until you compress the molecules together and it;s a bit harder than before. . .quenching undoes this. . .
