Whatever works for ya! I can load down, or go up. If the 338-06 AI trips your trigger, then go for it. Me, I'm more interested in hunting than worrying about a few feet per second one way or the other.
I could definately see the advantage to an Ackley over another wildcat though, if the caliber you were Ackleyizing was a common production cartridge. The 338-06 ain't though. The 338 WSM makes zero sense to me. I'd choose the 325 WSM over the 338 if that's what you're after.
However, there's a saying I've heard before, goes something like this. "To each his own..."
