At one time I had a very nice M-1910 sporter in .280 Ross, it was a well made rifle of both workmanship and materials. I experimented with removing and taking the bolt apart in a attempt to put it together wrong. What I found out and no one who writes about these says is "All you have to do if you have the bolt out is when you replace it in the rifle LOOK DOWN and you can clearly see the bolt rotate into battery. If you did it wrong it will not rotate.
Mike - yes, this is an important point that should help assuage people's apprehensions a lot. I mentioned it earlier: "...watch closely as you push the bolt fully forward, you can easily see that it is full closing and the lock lugs are turning..." Also, in his excellent 2002 Gun Digest article, "The Model 1910 Ross: The Best Rifle in the World" Jim Foral describes the same observation. So yes, simply "LOOK DOWN" and watch the bolt close. There is no need for guess work or to wonder.
