I am looking into buying a new rifle and getting into hunting after a two decade hiatus. Some of the arms that interest me are available in .280 Ackley Improved. Would it be possible to modify the combustion chamber to an actual .280 Remington? Could it be welded up, then machined to true .280 Rem.? I don’t want to fire the real .280 in the AI chamber. I also don’t know how I would reform the casing after it had expanded to the AI dimension. Yes, I am hoping to find a rifle in .280 soon enough to prepare for the 2021 deer season.
