I'm a huge fan of the Winchester Model-70. Between my dad & I we have quite a few.
I've read a lot of Positive reviews on the extreme weather s.s. & I've come to trust the Model-70.
Of the 5 Model-70's I load for, 4 shoot .56? /.680/.86?/& .813 five shot groups at 100. All EASILY SUB MOA. Thats an average of 3/4 MOA for 4 factory plain Jane rifles.
My other is a Model-70 300wby that occasionally shoots sub moa but averages 1"+/- 5 shot groups at 100.
So, ya I'd buy one in a heartbeat. It's a ready made package that looks to be ready to rock right out of the box without spending tons of $ to get it to l/r standards. Great tuneable factory trigger, great l/r stock, great action, Hard to beat that package.
You may note that my opinion is quite bias in favor of Winchester.
But they earned thier way into my opinion.
There's quite a few fans of the other brand you mentioned too. I like mine smooth, AND accurate, so thats one strike against Savage for me. They are rough as a Cobb, & feel quite a bit like thier pricetag, cheap. But a lot of guys love em, & they do shoot well on average. Ask bigngreen. He LOVES his Savages (hes also my buddy, so I'm sure hell chime in singing thier praises
)
You can't build a fanbase on accuracy without having accurate rifles, so Savage has earned thier reputation too.
In short you really can't go wrong with either Brand. All major manufacturers make a quality product, & occasionally a lemon slips thru, but the two models mentioned are known for being very accurate. So, besides a small bit of luck it comes down to personal preferance.
If a guy has a delima, you picked a good one to have
.
Good luck
