I have owned three model 70 extreme weather rifles. All were the USA made ones. Two were the short action (243 & 7-08), and one was the long action (270).
Here are my observations:
They all functioned perfectly, were very accurate, and well made.
They are NOT light.
The short action ones had smaller stocks, and felt good in my hands,(although I still found them a bit clunky), but the long action stock was very big and thick. It felt like I was carrying a 2x4..... It was the only reason I sold that rifle. Winchester dropped the ball when they put those big, heavy, fat stocks on that rifle. A featherweight profile stock would have been better.
If your style of hunting is hiking for hours, or climbing mountains, I don't recommend them unless you are a big man with huge hands.... If you drive around a lot, or sit and watch, they would be very good for that.
Remington 700, or LEMington, is a whole other thing. An older 700 is an excellent rifle. At one time that is the only rifle I would consider.
After buying two LEMingtons, a lvsf 22-250, and a police model 308, and shooting patterns, not groups, I decided I will never buy another LEMington rifle unless it was manufactured in the early 2000's or older. I've never had an older model 700 that wasn't super accurate.
This was not just my experience, I have a few friends that went through that same thing around the same time. (2008?)
When I went to the gunstore (wholesale sports) to inquire about my rifles, the store told me they had over 60 complaints about LEMingtons.
There is a reason that Remington went out of business.
Good luck in your search.
