The Winchester action will never be as smooth as a Marlin oh Hard One. This is the trade off for having machined forgings of the Winchester versus trepanned cold-rolled tubing and stamped metal parts on other brands. That said, the tolerances will be initially tighter to ensure a long lasting weapon with a long lasting fit.
I use RIG grease on the bearing surfaces which is wiped off to a degree before hunting to keep the crud down when firing ammo. I have noted RIG smooths it up a good bit.
Art Eatman is the man and can impart much more wisdom than can I.
As a Marlin owner, I can tell you I love the new Winchester product put out by the new owners: Fabrique National of Belgium. Remember: Winchester is a trade name owned by Olin.
