I recently came into a supply of .50 caliber slugs that someone had apparently been reloading into 50-70.
I don't intend to use these because:
1, they are way oversize for my rifle, and
2. they are way too hard, need a sharp instrument just to scratch.
If these bullets are linotype, I can use them with soft lead for a decent alloy.
It occurred to me that they might contain zinc.
Is there a simple way to determine if these bullets contain zinc?
I don't know that I would go to trouble of trying to remove the zinc if it is present, but that's putting the cart before the horse.
