[QUOTE="Lefty38-55, post: 2411838, member: 95029"] That analysis has been done ... tumbling brass is just not 'working' it! Think of bending a paperclip as an example of 'work'; as you 'moved' the metal beyond its parent state. Brass is a unique metal that is perfect for ammunition; strong enough to contain the explosion inside a rifle's chamber, yet soft enough to form to the chamber to prevent a gas leak. When it comes to hardening and softening cartridge brass (alloy C260), there are only 3 factors that affect the hardness. Those factors are: #1 The amount of [B]work[/B] done to the brass #2 The amount of [B]heat[/B] (temperature) applied to the brass #3 The duration of [B]time[/B] the brass remains [B][I]at[/I][/B] the elevated temperature.
