Love my 673. So far I've taken two big black bears with it one shot each. The biggest one shown in my avatar is 7 1/2 squared with a 19 7/16 skull. He was easily over an honest 400 pounds. The 350 RM is a decisive killer. Both bears went pretty much straight down at the shot. I use 225 grain Nosler Partition bullets.
For me I don't care for the muzzle blast from the 18.5 inch barrel on the model 600's. I think a M660 with its 20 inch barrel would be better. I recently bought a pretty pristine one in 308 in a local gun shop. As soon as I walked into the house my wife said thanks for buying me a new rifle. Easy come easy go I guess!
As a tribe the 600's & 660's have almost a cult following in western Washington for a long time. They're a pretty common sight. Here a short handy gun has long been popular in the timber. The kids now a days don't seem to go for them as much, they want the latest long range wonder. Problem is at least on the west side of the Cascade mountains long range is a bit limited.
If I wanted to spend the money I'd be tempted to go for one of the M7 full stock carbines Remington still offers through their custom shop. I like the M7 action. It's lighter and 1/2 inch shorter then a short M700 and has a little larger ejection port. To me it's a hunters action that in a real world hunting rifle is just as accurate as any M700. My 673 is by far one of my most accurate rifles and it's not finicky about what it gets fed. With one of the full stock M7's you would definitely have something no one else did.
Good luck with your search.
