Do the locking lugs engage in the barrel or the action?
The barrel - its a 3 lug action as opposed to the 6 lug action on the Sauer 101.
The other feature it has is a 14" LOP which suits perfectly.
Great rifle for the money.
If it's true that the bolt still locks in the barrel on the 100, then rebarrelling is not really any easier than on the 101 despite the threads. A good smith could get around the heat shrunk connection on the 101, the problem is supply of a barrel machined with locking lug recesses.
Are you sure the 100 bolt locks in the barrel?
