I have two 280AI's both custom rifles one with a 23" barrel and one with a 26" barrel. I am interested in loading them with the 168g VDL. Could you guy’s with experience with this caliber and bullet give me some load data and expected velocity. I remember Shawn Carlock built a 280AI and said it was good out to 800 yards, but he didn't list a load. I called berger and they E-mailed me standard 280 data but nothing for the 280AI. I would think maybe Retumbo powder would be a good powder to try, I know it works well in 7mm mag. Thanks for the help.
