I have contacted Redding, They were not helpful at all. I asked specifically about 280 AI and gave the part number, their response was they have been shipping dies since march of last year and keep an eye on major retailers. I again asked about 280 AI specifically and the second response was as useless as the first lol. Thanks ill give RCBS a try.
Yup, Peterson brass is incredible. I've got 200 pieces of once fired 280AI stuff. I'm hoping to get 10 reloads or so out of it. If not more. The loads I'm running aren't super hot.
