There is truth to that, all cartridges give up velocity in shorter barrels, but the smaller capacity ones tend to lose less than the overbores. That said, if you are going to burn an extra 45 grains of powder to gain 150 fps, why would you leave 200 fps on the table to save a few inches of barrel length?
