The '06 is a slightly overbore cartridge. It's not quite a magnum, but it shares the characteristic that longer barrels work better than shroter barrels.
My own pet '06 has a 26" barrel. My father's Springfield '03s were cut to 24". My opinion is that if you're going to a 22" or 20" barrel, you might as well go with a .308, except for the issue of heavier bullets in that shorter case.
You read the loading books, and max velocity from an '06 is generally with a 26" barrel. You can figure on a loss of some 75 ft/sec per inch of cut.
