Having a custom built hunting rifle in 7x57mm Mauser and it should be in my hands by next May. Here are some initial specs.
Shilen chrome-moly match grade barrel
about 24" from the boltface
98 Mauser action
The twist 1-9".
Timney Sportsman trigger
Model 70 style 3-position safety on the gas shield
The action will be pillar-bedded on aluminum posts, and the chamber area of the barrel and the front of the action ahead of the magazine gets glass-bedded.
Scope base and mounts will be Leupold or Redfield, with the action-bridge single piece mount and twist-in front ring, and windage-adjustable rear ring.
Richards Microfit stock in either American Black walnut, or English walnut, with rosewood forend tip and grip cap. A 1/2" thick solid rubber recoil pad and Monte Carlo cheek piece.
Hand-rubbed oil finish, of course!
