As the others have said, you have a pretty good list to choose from so it will really boil down to personal preference.

1. Remington 700 CDL...Had one in 270 Winchester....accuracy was ok and the overall quality was fair. The stock was inletted off center from the factory but Remington replaced for free.

2. Had a Browning X-Bolt Hunter....This was one of the most accurate rifles I have owned to date and was not picky about bullet weights. It is made in Japan. The only plastic I remember on this rifle was the magazine. Sold it to fund another rifle.

3. Kimber 84L....Loved the look and feel of these rifles and almost bought one but another rifle on your list(see Winchester M70) felt better to me.

4. Sako....Would love to have one but have only handled a few in the stores. Would probably be a great piece to hand down to the grandkids.

5. Weatherby Vanguard...Excellent rifles and I personally like the feel of them. Keep in mind though, the Vanguard is also made in Japan by Howa, since being made in the USA is important to you.

6. Ruger M77...Had an older M77 MKII "All Weather" a few years back. Great rifle that seems like would take a lot of abuse. Three position safety and controlled round feed...lots of pluses here. Not as accurate as I would like.

7. Winchester M70....Just recently purchased an FN made M70 Extreme Weather. So far it has proven accurate and the quality looks to be excellent. It had everything I was looking for in a rifle and felt great in my hands...so I went with it over the Kimber.
