I talked to my smith last night on this, he said that the diameter of the two is very close, the remington being slightly larger, Not completly removing the remington threads,he cuts the mauser threads over the top of them. the mauser threads naturally will be cut deeper than the rem threads. He then installs the barrel sets the headspace . He claims he has done this lots of times and it works. He is a very reputable smith and I don't have any reaon to doubt his word on this.
