The next best thing has already been built but how or when it gains popularity is another story. Have the 6mm and 6.5mm Creedmor gaining that popularity of course. Case design does offer a lot on this caliber. Near the same results as bigger case capacity calibers with less powder. Very hard to beat a 30 degree shoulder when maximizing case performance. Not jumping on this bandwagon because I already have a 6mm-284. Why add to the cost of components when I have a set up that will smoke the Creedmor.
