Beautiful and probably sleek and light DR. One would hope the frame and weight of the rifle matches the cartridge size.

While it would spoil its balance somewhat, a cartridge like that would cry out for a decent modern optic/scope. But as it is not fitted for one, only a fool would fit one now.

A 6mm DR should wear a decent 1-6x type scope or a small red dot sight.

A 6mm DR would make a dandy rifle for hog deer, feral pigs, goats, and especially roos in close country. And of course smaller deer species such as fallow, chitals, roes of course. Plus American whitetail. And where legal still would be a killer on reds and rusa. Many African antelope as well.
