40s-60s. Shoot whatever you got. Aught-Six, yo!
70s-80s. A few serious guys using Partitions. Everyone else, MAGNUM!!!! Oh, the Partition guys are MAGNUM! also.
90s-00s. Magnums! Short Magnums! Premium bullets!
10s. You don't need a magnum, just premium bullets. "Bullets matter more than headstamps."
