Nosler is good brass (mostly), Peterson is great brass In the cartridges I own including 280AI. Peterson brass comes prepped near perfect and I love that it comes in a reusable box. Keeps the necks perfect unlike others all thrown in a box and shipped while clanking against each other deforming the necks.
I've gotten to the point I just load the brass out of the box with zero prep for the first fire forming. Flash holes drilled about perfect and very uniform. Necks perfect and none bent or deformed. Pretty nice to just prime, powder, and load, then put right back into a perfect fitting box. Makes it easy to keep track of firings as well.
Good luck finding it though, especially in 280AI. Something special when you do.
