Not sure where this should go.
This would really bum me out. Just cleaned a couple hundred mixed, 1X fired WW and Starline 30-30 and 30-06, as I usually do, 1 hour with stainless pins in a Frankford Arsenal wet tumbler.
Also like I usually do, I dried the brass on a dedicated cookie sheet in our oven, intended 150F x 1 hour. It's a new to us oven and as it turns out, it was showing as 210F.
It came out heavily mottled - never happened before. I am thinking somehow it's probably all wasted, now. Even some blue-coloration, like an annealed neck - but it's all over every case, body, everywhere.
-even though 210 is over my usual 150F - that's well below any danger zone. What's happened? And is it now trash?
