Going to rebarrel my 270 AM to a 338 Edge. Just don't have a use for it. Have a Hart barrel ordered for the project. Will finish at 30" including brake. I hunted this year with a Rem 700 LSS 338 RUM 26" factory barrel with some success. Love this round. I'm toying with the idea of re-chambering my RUM to an Edge. My reasoning is to try to avoid any posible confusion with the ammo. Both rifles will be going on some of my trips. Although I still plan on using the 225 gr Accubond in the LSS and the 300 gr Sierra in the new gun. Identifying the ammo should not pose a problem. Then there is the remote possibility both rifle may shoot the same load--wishful thinking!! I'm getting just over 3100 fps with the 225 gr Accubond using RL-22. This is my zero. Another load gives me a tad over 3200 fps w/ RL-25. Ballistically would I realize any gains to warrant the new chamber in a 26" barrel. Your thoughts will be appreciated. light bulb BTW; Any one with an interest in the 30" AM barrel, it has 400 rds through her make an offer.
