Just picked up 2 boxes of 338 RUM brass and so far I'm happy With what I see. I haven't loaded any yet I just got home and checked it out last night. If it's everything it appears to be, and as good as the reviews I'll be buying more for a lot more cartridges.
I use the 338 RUM brass in a couple different wildcats and it's holding up very well. I'll likely start switching over to the ADG brass in whatever chamberings I can.
