Powder capacities are for all intents and purposes identical. Which makes sense, because the case was intentionally created from it's inception to that very thing, but at a length that would cycle through the Winchester model 100 auto loader.Ballistically very very similar to the 30-06.
However, if built on a long action, bullets can be seated "optimal" and still fit in the magazine.
It would be a not quite magnum for 30 caliber.
67.2 grains of powder vs 30-06 67.1
