6.5CM vs .308 as it pertains to this forum

[Tim K]

The "ops question" is why I would stick to 5.56 and/or .22LR. and 9mm

Exactly. .223 ammo is almost exactly half the weight of .308.

Heavy precision rifles make no sense if you're concerned about bugging out on foot.

Heavy precision rifles make no sense if you're concerned about bugging out on foot.

BUT, if you're no going anywhere, OR you have a defensible area with good visibility, maybe that precision rifle is exactly the tool you need! Every situation is different. If the world was ending, I would love to be in a situation where I can enforce a standoff distance of 600+yds. I would also love to never have to point a gun at anyone, ever. Both of those things will likely be outside of my control.
