Best to start with a Mauser until you get a grip on what is going on. You can get into trouble with the extractor cut out (Model 70, Arisaka, ect.) on some barrels. In Guffy's weird rambling way, I think he is trying to warn you about case head support. The less case sticking out of the barrel when the bolt is locked the better. If you look at an average rimless case, the head is solid brass. The wall of the case expands but not the head (Unless there are other major problems). The wall of the case must be supported by chamber.
