I'm considering re-barreling my 280 Ackley to a 6.5-280 Ackley. My 280AI's accuracy is starting to open up. Its last health check up showed severe fire cracking in the throat area. It still shoots MOA but was once a one hole gun. I have a pile of Berger 156's and thought the 6.5 would be a fun cartridge. Any thoughts or anyone want to talk me out of it? Should I stay with the 280 AI?
