Bolt guns can so out distance that thing.
Ill stick with my M700
I'll agree with that. But...
That's not what's needed as much as an SVD type rifle. Think about it. Iraq.
The M700 is the kind of rifle where you make long-range surgical strike. That is for a different type of sniping. For stalking. That implies a totally different type of engagement. It is more of an ambush/assassination type strike on a higher value target. That implies you expect a target in a certain area, and that you've been surveying the area waiting for opportunity. Have the time to prepare for the shot and the target is not expecting it.
In urban guerilla war, that's not the case. In combat no targets are just standing there, or typically are not standing there. Distances are not often going to be 1,000m.
What is more useful is an "accurate-enough" semi-auto. Something to drop badguys fast. Something with quick followup shots. Something you can deliver lead with down 600-700m with good accuracy (center of mass shots) and do so quickly on multiple targets.
That applies to open terrain also. You get a group of insurgent/terrorist fighters on a hill like in Afghanistan, and you need something accurate, with range and fast. They've been fiddling with these 77gr 5.56's...but the 308 outclasses it at distance.
I think this is a good move. They go through the trouble of getting a match-grade barrel, freefloating, adding a Leupold, custom stock and all this stuff on a 5.56 to shoot out to 600m ...why not just build a good .308 Stoner? That's what it was originally suppose to be. Hits harder, better downrange with less wind effects. I think the .308 takes more advantage of all the accurizing and customizations and optics.
