Thread: Safest Method Of Discharging Unknown Primers?

I haven't looked at second hand brass on TM for a few years now, but when I used to, for some reason, everytime you see brass advertised on TM, it is almost always 'once fired' even on multiple different listings from different sellers where the photos show three different types of primers. Partly why I stopped shopping in that particular category.
@Hugh Shields, I am happy to put your brass through my ultrasonic cleaner if you think that would be helpful with the oil. Unless someone in Wellington chimes in with a similar offer, feel free to PM me and we can figure out a way to get the brass here.
