My version of what you describe is a Ruger 77 Stainless/Zytel in .35 Whelen and cut to 20" with a Remington front sight and NECG rear ghost ring.
It is scoped at the moment for load development. I may keep it scoped and just keep the NECG handy for a backup situation. I have been playing with 225 grain loads (Sierra and Barnes) as well as 158 grain pistol loads. Seems to be a very handy and versatile low maintenance rig as long as ranges are reasonable. Hopefully in another 15-20 years of guiding my kids around Montana it will have some of the character you described in the guide's rifle.
