30 is 0.110" longer at the shoulder. It'd work but the 33 Nosler case gives just a little more room to chase lands or seating adjustability. It gives about 88gr water capacity with a bullet at the neck/shoulder junction.Did you compare it to the 30 nosler? I was under impression that the 26/28 had same shoulder, and the 30/33 had same shoulder. In that case, start with the 30 and save a step in neck in down? Just a thought.
