After reading a lot of the info available on the various 408 based calibers, I have noticed no attempts at just improving the 408 itself. Is this mainly due to not much in the way of bullet selection? Is all the bad press that Chey-Tac brought on itself a real factor as well? With the real velocity gains that have been seen in 338 and 375, I would thing a 408 400gr at 3100 with a BC in the .9-.93 range might be impressive. Any thoughts?
