I would go with Weatherby.
Longer barrel, better resale and less likely to get a lemon.
I have heard forever how the 700 action is the basis for this and that but I feel QC at Remington is alot more likely to let a turd slip thru and don't want to be the one to find it.
When I was shopping for a 7mm-08, I wanted a Rem LSS in the worst way but bought a Tikka instead for the reasons posted above and don't regret it.
Rem trigger will need work too, even if the barrel/action is spot on.
come to think of it, why not a S/SS Tikka 7MM magnum?
