Thread: Annealing Privi and S&B brass

Just annealed brass from different manufacturers, and found both look different.
The S&B brass has a distinct colour change, bit like Lapua does.
The Privi stuff has less of a contrast, colour wise.
Both annealed exactly the same
So, does S&B brass have more copper in the 'mixture' ?
Thoughts ?

PS, both reload, and shoot, fine.
