Thanks I am going to see if I can find retumbo
I would also look for IMR 7828 SSC. I have excellent luck out of both my .25-06 AI and .30-06 AI with it and heavy-for-caliber bullets. Those calibers are on both sides of the .280 AI, and in my mind, logic would dictate that it would work well in it, as well.
