Does anyone know anything about this chamber? I don't think Ackley ever 'improved' the 308 but I have seen the 'AI' tag given to it. As far as I can tell, it is just the .308 with a 40deg taper and a straighter body. Anyone know??
I need to recut the chamber in my 308 and thought why not the AI over standard?
