I like that remington 700 mountain from what I can see.

6.5lbs plus scope sling ammo etc... 7.5-8.0 lbs in 7mm-08, 270, 280.

I'm over the idea of carrying a 10-11lbs magnum rifle instead of a 8lbs 270win.

Big long range type magnum calibers are going to kick, so to reduce that you need weight or willing to take the abuse.

I say unless you need a big heavy magnum, get something like the above cartridges.
