The T3 will be lighter, cost less, and has a good chance of being more accurate. It comes with rings. Downsides of a T3 are the magazines are around $75 each, and it is not a Winchester.
The Model 70 is an excellent rifle.
Try handling each and see which one feels best.
No bad choices here.
I'll take the one size fits all, foreign made, here!!
The Winchesters are an American icon no doubt, but wonder how many know that they are built in the U.S. by a foreign company?? Time will tell if the "new" Winnies will carry on the Winchester tradition??
