Hi folks, new to the forum and seeking wisdom!
I sonic cleaned a bunch of brass from last range session (45-70, 44m, 45acp and 6.5cm), rinsed under hot water then put in the oven 150 for a spell to dry. It's always worked fine but this time ... I forgot to take it out. Next day I put the oven on to heat up for dinner at 425 degrees. Oven heated up then after about 10 mins at 425 I went to put the dinner in. Oh joy, a baking sheet full of slightly discolored brass!
So my question is, have I cooked it and need to scrap it? I've read that brass doesn't alter structurally until it passes 600 degrees but it all had that slight 'case hardened' look to it.
I don't want to scrap a load of good brass but also don't want to deal with split cases and head separation deals.
Any thoughts?
