NOV.,
Unless you're going to hunt dangerous game, the Mauser style one peice bolt with its non-rotating claw extractor and controlled round feed, is really not needed. It was designed for battle and the thought behind the controlled round feed was to keep battle rattled troops from short stroking and tying up their rifle.
Don't get me wrong here I'm a very avid Mauser fan, in my opinion there is no finer action. But you can spend a lot more on that type rifle for no actual advantage, over modern Remington, Savage actions.
Unless you're planning hunting something that bites back, the precision fit of lapped bolt raceways and lugs and short lift(fast second shot)are of little use other than knowing you have the best of the best.
I like a bolt that I can operate without banging the scope around, most now days are designed with enough clearance, where on older sporterized military actions bending or reshaping the bolt handle was neccessary. The bolt lift 90 degrees vs 60 degrees just give a faster second shot.
You should be able to cycle the bolt fast with out the lugs binding in the raceways.
If you have made a caliber choice, I woul get at least two dummy cartridges from Azoom or another maker and take with me to the place where you are going to buy your rifle ,cycle them through the action, also make sure if you're going to use a scope that it has a scope mounted ,that way you can tell if you like the way the bolt lifts in the presence of the scope.
