The new FN produced Winchesters are the best ever Winchesters
I'm a huge Model 70 fan. I have several, pre-post 64's and the newer FNs.
I found the above statement to be true.
I like Winchester Featherweights, As we know, you can;t shoot Featherweights for extended periods as they get hot and start walking. For some reason, My FN Featherweight in 270 doesn't seem to suffer this problems, as least not as bad as my other feather weights.
I don't know about the Extreme rifles, I'm more into conventional blued rifles in wood stocks.
I personally don't have any experience with the 300 WSM. I do understand the Army Marksmanship Unit is making long range rifles with this caliber, that tells me its not a dog, they don't play with rounds that don't work.
You didn't go wrong with your model 70, you'll be pleased.
And no, I don't sell Winchesters, I just buy them
