Details

The Redding Saeco Lead Hardness Tester can give reloaders accurate feed back as to the hardness of the lead they intend to use for casting bullets.  Soft lead pushed at significant velocity has a tendency to “lead the barrel” of your firearm leaving a smear of lead inside which drastically affects accuracy.  Increasing the hardness of the casting mix by alloying pure lead with other elements like, tin and antimony or by quenching the cast bullet will increase the hardness of the projectile.  But increase it to what?  The Redding Saeco Lead Hardness Tester can accurately measure the hardness of the alloy for casting. 

 

It will pay for itself time and time again by quantifying the hardness of an alloy mix.  Bullet casters can convert scrap lead into an alloy of reliable and known hardness in a consistent and repeatable manner.

 

The Saeco Lead Hardness Tester uses a hardened steel indenter to penetrate the surface of the test material.  By determining the depth of the indentation reloaders can determine the hardness and can interpret the measurement from a vernier scale.

Saeco uses a calibration scale of 1 to 10 where 1 indicates soft material such as pure lead and 10 indicates hard alloys like Linotype which is used for high velocity magnum pistol bullets or gas checked rifle bullets.  Commonly wheel weights are an excellent source of lead alloy for bullet casting.  Typically wheel weights register a hardness somewhere around 7-9.
