Remington is a favorite because it never has crimped pockets, has pretty good case capacity, and generally comes from the factory with annealed necks. It sizes easily and I never get splits, even though I usually load at max.
Easier to list my least favorite. That would be PMC. Often the base is quite thick, which reduces case volume, making my full power loads into compressed loads. And the PMC contract ammo headstamped AD is extremely difficult to decap.
List of favorites and reasons why:
My favorites have good case capacity so the powder stays below the neck on full loads. Remington is pretty good and never has crimped pockets, case capacity of Winchester varies a lot but it's good brass with long life, RORG is pretty good and often can be reprimed without reaming the crimped pocket, Federal is OK, Lake City (despite predictions that mil brass is thicker and thus has less case capacity) has more capacity than most commercial brass but usually has a tightly crimped pocket. Most folks won't believe that LC has greater capacity, but measure it and prove it to yourself.
