A 6.5 PRC/Saum/Sherman is plenty capable based on both terminal and external ballistics. The reality is that 99% of the hunters are not capable. If a person is in the 1% then good for them. I highly doubt I'll ever tag an elk at 1000 at any rate, not a 1%'er. The 6.5 is fairly light for that range regardless, I agree with that. I think the issue with the 7, I have a couple, is that a guy really needs to be in the heavies and most don't buy a rifle with a fast twist barrel. They wind up with a 140-160 class bullet and dismiss the science. Those running 180-190 class know that a 7 is pretty sweet. It's definitely one of my fav's.
