I have recently been doing a little personal research into large caliber "tactical" rifles. I have found that 2 cartridges are possibly the best for the purpose. But i have found conflicting information about each of them. Maybe its just manufacture promotion or the article writers personal preference. But i have found that .408 Chey-Tac and .416 Barrett are the 2 best long range "tactical" rounds out there followed by the .50 BMG. i haven't really found anything different between the 2 rounds, other than a few minor details that can be worked around with different loads. The 408 is slightly heavier by 19 grains, 250 ft/s slower. The ballistic coefficient of the barrett is 1.103 and the cheytac is .934. So since these to rounds are so similar which one would you use if you were a "tactical shooter" or just a long range hunter with a lot of money.
