You cannot take two cartridges with two different shapes, two different case capacities, two (or more) different firearms/barrels and reach a proper scientific - let alone remotely objective - conclusion. First of all your comparison has far too many variables to make a valid argument and your sample size is far too small. I also refute your belief based on my own subjective experiences.
With the exception of some brilliant ballisticians devoted to the study of bullets and their flight, there is a sad lack of proper scientific research into anything pertaining to shooting hardware. Cartridges, actions, Barrels, bores, break-in....these are all full of opinions, but all lacking in credible research.
Sorry... I am cursed with a background in utilizing evidence based research. This flies in the face of a hobby and consumer industry that is almost completely based on "follow the leader" and the seeking of validation for one's consumer choices.
