Doesn't really seem like a recipe for commercial success to me. Why make a standard catalogue offering for a very limited market of shooters that would just come on the fire complain about he barrel quality and then spin on a $600 custom barrel on a $500 rifle anyway. Face it there's nothing these chamberings have to offer in terminal performance that the 6.5 offerings don't already provide and vice versa. They all throw sub 30 cal bullets that weigh within 15-20 grains of each other operating within a couple hundred feet of velocity window. Any practical difference is in the shooters imagination and not noted by game or a steel chicken.
