So this topic has been haunting me for years and i was hoping i could get some clarity. The M200 .408 has been proven it is more accurate than the M99 .416. However, logically the .416 Barrett cartridge has a significantly higher ballistic coefficient than the .408 Cheytac as well as much higher velocity and therefore should be more accurate, right? Im not sure about this, but I'm guessing the M99 is not as accurate as the M200 because they don't true the action and spend the time making everything precise on the rifle. <span style="font-weight: bold">Now what if you put the .416 Barrett in a precise rifle? Would the .416 be more accurate? </span>Also i just found out McMillan offers the Tac-50 in .416 Barrett which should be interesting to see how the accuracy differs from the M99.
