I've always enjoyed my model 70's (2). They've been sub moa out of box. Adjustable triggers, nice feel, 100% reliable.
I shoot one of them long range. I bought a Boyds thumbhole stock ($80), bedded the action, and worked up a load. My load will shoot .3 at 100 (3 shots). I shoot this rifle to 1K. Very happy with it!
I don't believe the Winchester name will die.
If I was going to shoot grizz with a 300, I'd use big x bullets.
