I don’t know where the other data came from.

I just took the information that the original poster posted, and did the math.

Two seemingly identical bullets, one is lighter. Why? Because the alloy is less dense.

I took his post to mean he acquired some bullets that were different, and couldn’t figure out why. And wanted to know what the mix might be.

Never saw, or read anything other than his first request for help before I grabbed a pen and a napkin.

Composing a reply that would defang the peanut gallery took longer than solving the equation.
