That's probably part of it, but I think if you look at the pro vs cons in the types of hunting scenario's the target audience will likely be in, there is little benefit. Shots under 400 yards don't need every ounce of FPS or energy squeezed out. Plus it adds weight, cost, and awkwardness to wield in the field.Yup you are probably right on the targeted audience, but why wouldn't you give a caliber the best barrel length to help it preform to its potential. Can't cost that much more to add 2" barrel length. But I suppose 2" cost adds up on thousands of rifles. Oh well I wish them well on their builds!!
