As far as I am aware... Remington and Winchester cases are not annealed from the factory. . .
Not so, Paul. Modern factory centerfire brass cases are annealed several times during manufacture and normally receive a final neck/shoulder anneal that would show colors if it weren't polished off during a final tumbling operation before loading. U.S. manufacturers ordinarily perform this final polish on their commercial cases (military specs require the color to be visible, so this step is omitted for GI contracts).

Prvi Partizan is a bit notorious for inconsistent final anneal. New PPU cases often require another anneal before expanding to a larger neck diameter.

For small-scale home annealing, the best advice is to keep it simple. All that's needed is a propane torch and a metal pan or sheet to protect the work surface while cases air-cool. Most classic military rifle cases are long enough to allow the neck and shoulder to be nicely annealed while holding the other end in in the fingers. Brass being a good heat conductor, there's really no need for rotation - just direct flame at shoulder, not neck or mouth.
