It makes sense. Most guys are trained to shoot out to 1000. The military at least the usmc calls the 7.62 effective out to 800 with a bolt gun. If switching to 6.5 cm helps a bit with trajectory and wind drift then why not provide a rifle that will increase 1st round impacts? These guys are not created equal and anything that will help the average end user should be considered. They have access to other platforms and calibers. No one jumps up and down volunteering to carry a m107 up a mountain. The lighter and easier the rifle is to shoot, the better. You really think a 147 to the chest won't do the same as a 175 smk? Both will kill you.
