Close enough to your goal to not worry about the AI part.
Unless you want an AI....
There's a constant drum beat on these forums that AI chambers aren't worth the trouble. If you are talking about AI'ing a factory barrel, I agree - the gunsmithing bill won't be worth the added benefits. But if you're talking about cutting a chamber in a virgin blank, an AI chamber can be cut for the same price as a standard chamber.
It's only 50-75fps more velocity for an AI over a standard, but more is reliably still more. Not having to trim brass anymore is a nice added bonus. Factory ammunition shoots just fine in an AI barrel (my fireform loads are very accurate). W/ a hand lapped custom tube and a tight chamber you will get about the same velocities as a factory tube in a standard chambering - my 7mm-08AI w/ Hart 23" barrel routinely shoots a little faster w/ factory fodder than published velocity.
Really the only down side is fireforming the brass. If you're the kind of person that puts at least 100rounds down range in the off season, it's a non issue. I doubt I will ever chamber a custom tube in a standard chamber for a bolt rifle again.
