I see it posted over and over that a just a little zinc mixed in a melt will ruin your alloy. Yet I have never seen anyone post a definitive reason why it does this, or how much is a little.

An inquiring mind would like to know:

Exactly what’s a little?...... An ounce to a pound?...... A drop to a gallon?...... A milliliter to a barrel?

Exactly what does it do to ruin it?...... Make you run higher temps to cast?...... Makes bullets too hard to size?...... Changes the weight?

No speculation, just the facts.
