It should not matter if they gaul a little if you are going to rebarrel, since the threads in the action will be trued anyways.
the only time I ever have seen threads get damaged on a Remmy of any kind is when someone forgot to take the plug screw out of the first base hole. It was in far enough to rub on the barrel threads. Both barrel and action threads suffered for this, but when the acion wa trued, it didnt make any differance.
