Just because it's shorter, doesn't mean it will work any better. The bolt diameter is the same as the standard short action, and that's where the problem lies. For short cases with a small boltface, the whole action needs to be scaled down. The bolt diameter needs to be smaller as well as the diameter of the lugs, and the thickness of the lugs. A short case requires less jump to get the nose of the bullet started into the chamber mouth, and thus the magazine must be closer to the breech. A smaller diameter will also limit the deflection angle of the case when the ejector tips it out.
