A light charge of fast burning powder will reach peak velocity sooner and begin to drop pressures below the point of further gains; so that 16" barrel may very well shoot faster with such a load. However, a heavy charge of AA-9, IMR-4227, H-110 and the like will make the longer barrel shoot substantially faster.
