Yes, MLs are basically obsolete. In some European countries they are just easy to obtain and require no registration. They would not be my gun of first choice.
I hand load .44 Rem Mag, .45 Colt, 6.5x55 and 7x64 Brenecke (if I were American that would probably be a 30-06). I agree that the straight wall cases are easy to load and long lasting. Necksizing and annealing makes the 7x64 brass last longer and requires almost no trimming. However I might go for full sizing when I load for a group. That will allow for interchangeable ammo.
