Bob: I would suspect the difference is caused by a difference in the gap between the cylinder face and the forcing cone of the barrel between the two pistols.
Sorry, I don't buy that. That being the case, all loads should have similar results. They don't. Only certain powders exhibited that result. H110, for example, showed significant increase with the longer barrel.
