I went for years loading rifle ammo without a case tumbler. Acquired the machine when I started reloading for handgun. Anyway, ran some 7mm-08 Rem brass through the case tumbler. I was struck dumb at how much more easily these shells entered the full length sizer die. I kicked myself in the butt for not discovering or realizing this decades sooner.

As previous posters have said, keep everything clean. Tumbling your brass is like icing on the case, makes them slick as goose dung.

Incidentally, persistent comments and rumors indicate that the Remington autoloaders are designed for once-a-year eastern deer hunters and engineered for a useful life of about a 1000 rounds. For big city hunters where the nearest 100-yard range requires a full tank of gas to reach, Their rifles will see little use. But I do have a friend that wore out a Rem 742. Remington offered a trade-in allowance, not a new gun.
